Wiring to the circuit breakers is 220 volts. The circuit breaker box has 2 110 Volt lines. If you connect two black lines together from one side nothing happens. If the these two black wires are from different circuit breakers you may have a safety issue by back feeding the electricity.
If you connect 2 different 110 volt lines you will end up with a short. This ends up as a 220 volt short.
When two hot wires are connected, it creates a short circuit which can lead to excessive current flow, overheating, and potentially a fire hazard. It is important to never directly connect two hot wires together without proper safety precautions and electrical protections in place.
If it is a white wire with just a black end, the black is tape. This is done to show that it is a return hot wire to a fixture or switch. Smaller wires in appliances can use many different combinations of color.
If you are talking about the two wires when looking in a switch junction box or light junction box they will be the switched leg. The white wire is supposed to be identified with black tape to show that it is a current carrying wire but in a lot of cases this does not get done.
This sounds like a typical light switch connection that turns on an overhead light fixture. There are two pairs of wires in from the supply voltage and two pairs of wires out to the light fixture. The two white wires are connected together in the back of the box. These are the neutrals from the supply to the light fixture. The two black wires are the ones that get attached to the switch. Incoming "hot" to the top terminal of the switch and the outgoing black to the bottom terminal of the switch. If you just touch the two wires together as you explain in your question then the light fixture should come on.
Depending on how the two wires are connected in the circuit ,one scenario is the breaker to that circuit will trip.

When connecting a 240V line with two hot wires and a ground does it make a difference if the red or black hot wires are connected to L1 or L2 for a jet pump pressure switch?
No, it does not matter which hot wire (red or black) is connected to L1 or L2 for a jet pump pressure switch in a 240V setup. The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
What side of the outlet do the red and black wires go on 220 outlet?
In a 220 volt outlet, the red and black wires are typically connected to the two hot terminals of the outlet. The white wire is connected to the neutral terminal and the green or bare wire is connected to the ground terminal. It's important to consult a professional electrician to ensure proper installation.
Why would a light switch have two black wires for power and two whites caped off?
Having two black wires connected to a light switch indicates that it is a switch loop, where one black wire brings power to the switch and the other black wire carries power to the connected light fixture. The two white wires capped off are neutral wires from the power source and the light fixture, which are typically not connected to the switch.
How do you determine which wire is hot at a switch that has the white wires connected to each other and two black wires from different romex going to the switch?
The wire that is connected to the black screw terminal on the switch is the hot wire. This wire is carrying the electrical current to the switch. The white wires connected to each other are neutral wires that are not carrying current.
You touch two hot wires together breaker box will not turn back on did you burn the breaker out?
Touching two hot wires together can cause a short circuit, which may have damaged the breaker. It is important to not touch hot wires together as it can be dangerous and cause damage to the electrical system. If the breaker will not reset, it is recommended to call a licensed electrician to assess and repair the situation.
Why there must be two wires connected to an ammeter?
Two.

The important thing is to ensure that each hot wire is connected to one of the two load terminals of the pressure switch. Make sure to also connect the ground wire for safety.
Where are the hot wires on a Geo Metro ignition?
im assuming your looking for hot wires on the coil. They should be two wires of the coil
True or false-computers are connected with a network of wires on the internet?
Most are connected by wires, some are connected by a wireless connector ('Dongle'). Two of my friends have wireless dongles.
What side of the outlet do the red and black wires go on 220 outlet?
In a 220 volt outlet, the red and black wires are typically connected to the two hot terminals of the outlet. The white wire is connected to the neutral terminal and the green or bare wire is connected to the ground terminal. It's important to consult a professional electrician to ensure proper installation.

Will electricity pass through 2 wires?
Yes, electricity can pass through two wires if they are connected in a circuit where there is a complete path for the electricity to flow. If the wires are not connected in a closed circuit, the electricity will not flow between them.
Which wire goes where on 220v socket?
If there are three attachment points then you have a ground and two hots. The ground goes to the green screw and the hot wires can be connected to either hot screw. If there are four wires then the hots will likely be red and black. The white wire is the common or neutral and the green or bare wire is ground.
You touch two hot wires together breaker box will not turn back on did you burn the breaker out?
Touching two hot wires together can cause a short circuit, which may have damaged the breaker. It is important to not touch hot wires together as it can be dangerous and cause damage to the electrical system. If the breaker will not reset, it is recommended to call a licensed electrician to assess and repair the situation.
What if the new light fixture has 2 black wires and no white wire?
If the new light fixture has 2 black wires and no white wire, it likely means that the fixture is designed to be connected to a circuit where the white wire has been designated as the hot wire instead of the black wire. Make sure to double check the wiring and consult a professional if you are unsure.
What is meant by 220 volts AC?
In US household electrical service there are two "hot" 110 volt wires and one ground. Only one hot wire is connected to a normal outlet or light fixture. To wire a 220 volt alternating current outlet, both hot wires are connected to the outlet. This is used for appliances that need more power than is provided by 110 volts like electric ranges, clothes dryers, air conditioners.
