What do you call a diagram that shows the electrical connections of a circuit's components?
Schematic or Circuit Diagram.
What is the difference between loop start and ground start?
The typical analog circuit that connects between the customer premises and the central office (phone company) has two copper wires. These wires are referred to as TIP and RING. There is typically a -48 VDC signal between the TIP and RING wires which is typically powered by the central office switch. When a standard analog phone is connected to the analog circuit and the handset is picked up (going off hook) a switch on the phone closes the connection between the TIP and RING wires and current is drawn from the central office switch. The switch determines that current is being drawn and provides dial tone so the person on the phone knows it is time to dial a number. A PBX FXO circuit running loop start looks like a standard analog phone to the central office switch. Now, one problem that is often seen with loop start circuits is a condition called "glare". Glare occurs when a call comes in on the analog line from the central office at the same time the PBX wants to seize the same line to make an outgoing call. The ground start protocol was designed to eliminate this problem with glare. From the PBX side, the RING lead is grounded first, then the central office circuit must ground the TIP lead before the PBX can close the loop between TIP and RING.
What would cause a circuit breaker heating element to trip off?
There are two conditions that would cause a breaker to trip off. One is an overload of the circuit and the other is a short circuit on the circuit. The heating element within the breaker is what monitors for circuit overloads.
What do I do if there is no circuit breaker for outdoor light?
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.
Where is the high side of transformer on open circuit test?
high voltage side call primary
If a circuit has wires coming out what should you do?
Call an electrician
What do you call a fuse with two black wires attached?
A fuse with two black wires attached is typically called a "black wire fuse." The black wires serve as the connections for the electrical circuit, with the fuse serving to protect the circuit from overloading or short circuits.
How does cellphones call Without wires?
They use a radio inside the device to communicate with a tower. That tower connects to the carrier's network, and from there is forwarded to another carrier's network. Basically the receiving end is the reverse of the sending.
What do you call something with no wires?
Something with no wires would be wireless.
What do you call a circuit when the switch is open?
An open circuit....
What do you call the thing that attaches the jewel to a chain for a necklace?

What do you call the blood of computer?
Wires
What song connects to the book Call of the Wild?
rawhide!
What do you call a copper connecting two poles in circuit?
A copper connecting two poles in a circuit is typically referred to as a "conductor." Conductors allow electricity to flow between components, facilitating the transfer of electrical energy. In many cases, copper wires are used due to their excellent conductivity and durability.
