What else can I help you with?
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?
Answer for USA, Canada and countries running a 60 Hz power supply service.The white wires are the neutral wires. One of the black wires is the "feed" hot wire coming from the circuit's breaker on the incoming power panel.The other black wire is the "switched" hot wire going to the load. (The light or whatever appliance the switch is controlling.)If you don't know how to tell which black wire is which, the hot is usually the wire connected to the top screw on the switch. In Canada, there is a rule that all hot wires are to be connected to the top of switching devices.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
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 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.
What is the hot wire white black or green?
The hot wire on a lamp cord will be the the side that has the more narrow prong on the plug-in. Or you can look at the cord and whichever side is smooth, (not ribbed but smooth), is your hot wire.

I don't believe you can determine that all i know is that for thousands of years when white people mixed with black people if you looked black just a little you was considered black. only because Black Dominate white genetically any scientist who studies Genetics will tell you that. the Genes are stronger genetically.

Why are your ground wires black in the panel box of your home?
Ground wires are typically bare wire or green covered. Common wires are white and hot wires are black. If you have black wires that are grounds or commons you should contact an electrician to ensure you don't have a problem on your hands. Sounds like someone who didn't know what they were doing has been mucking around in your panel.
