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.

What is the result on the meter reading of clamping the jaws of a clamp-on ammeter around two wires?

If the two wires are on a parallel feed you would read the current through the parallel feeders. If the two wires are "hot " to the load and return back from the load the meter will read zero. The two magnetic fields that surround the wires when a current flows through them will cancel each other. As a result of this there will be no magnetic induction induced into the sensing coil of the clamp on meter.


When will a telephone wire be longer summer or winter?

When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.

You went to change out the stereo in your 2003 tacoma and somehow when messing with the dimmer wires on the stereo you have no dash lights and your tail lights fuses are blowing when theyre messed wit?

I'm not sure if this is the same but the ground wire going to the stereo is not really ground! Try running the hot wires for your new stereo right to the fuse box or straight to the bat and see if that cures it. I had a problem that was very similar but it wasn't a Tacoma.

How can I fix reversed hot and ground wires in an electrical circuit?

To fix reversed hot and ground wires in an electrical circuit, you should first turn off the power to the circuit. Then, switch the wires so that the hot wire is connected to the hot terminal and the ground wire is connected to the ground terminal. Finally, turn the power back on and test the circuit to ensure it is working correctly.
