What does it mean when the circuit tester light does not come on when touching the black and white wires?
It could mean two things. The first thing would be that the tester is not working. Test on a circuit that you know to be energized. The second thing causing a tester not to light is that the circuit under test is de energized. When using these types of testers always test the black to white wire and then black to ground wire. If the tester indicates there is a voltage to ground and not the white then the neutral white wire is open somewhere in the circuit.
If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot wire?
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
What color is common wire?
Normally the white wire is neutral, and the black is hot. But if the power comes into the ceiling box and the light is controlled by a switch leg the white my very well be hot. If there is only one wire in the switch box that is a switch leg.
If there are 3 wires - green black white and you know that Green is the ground. Which one is hot Black or white?
=== === A Black wire can be the "Hot" wire of a 120 Volt supply.A White wire is normally the "Neutral" wire.A Green wire (or bare wire with no insulation) is normally the local "Ground "wire.IF YOU ARE NOT ALREADY SURE YOU CAN DO SOME ELECTRICAL WORKSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.=== === If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
Hot wires in home wiring are normally colored and ground wires in computers are normally colored?
Hot wires in home are normally colored black. And ground wires in computers are normally colored black as well.
What are the uses of black wire?
The black wire is not really needed in a circuit because it has a negative voltage
How is a volt meter connected in a circuit?
It all depends on what you are trying to achieve or measure. To find spot voltages around a circuit, it is normal to measure with reference to a common rail or ground. Attach one lead (normally black negative) to a common ground, chassis or negative point, then probe with the red lead to check spot voltages at test points. If you are permanently rigging a voltmeter in a circuit, it is usually there to monitor power supply voltage. It should be wired across the output of the power supply or across a battery. ie connected directly to the poles.
What is a Thevenin's equivalent circuit consists of?
A Thevenin's equivalent circuit is a single voltage source in series with a single resistor. It is electrically the same as any combination of voltage sources, current sources, and resistors that, as a black box, has two terminals. The technique is useful in simplifying circuits, when analyzing them.
How do you know electrical is grounded?
I test it with a digital multimeter. Set it to measure the voltage you're expecting, verify that the circuit is powered (put the red probe to the positive side of the circuit, and find a different ground), then move the black probe to the intended ground. You should be reading the voltage you're expecting if the ground is good.

What is the procedure to connect two circuits without losing the output voltage of first circuit which is transfered to the second circuit?
I assume you are talking about 120volt electrical circuits ???? If so, just wire them in parallel. In other words, connect the black wire to line side on each circuit and the white wire to neutral on each circuit. The bare ground wire goes to ground (green) At each circuit will be 120 volts AC. Do not exceed the maximum current of the circuit breaker supplying the current (typically 15 - 20 amps)
Can you attach a single wire of an exterior fixture to a double wire that is in the electric box?
In a box it is common practice to join two black wires, two white wires and two ground wires, for example, to extend the circuit to another location. Provided you don't overload the circuit it is okay to put 3-wires into the comparable wirenuts for your external light. There are some added caveats including not exceeding the number of wires designed for the box (usually 4); and outside circuits normally require a GFCI circuit for safety.

Do black panthers only breed with other black panthers?
No. A black panther is the melanistic (black) "version" of a jaguar or leopard. A black jaguar will mate with a normally colored jaguar just as a black leopard will mate with a normally colored leopard.
