1.5 multiplied by 4 = 6.0
A electrical voltage of Fifteen Volts.
It depends on the value of the three resistors. If they are equal, then each resistor has 5 volts across it.
About 5.5 volts.

most computers use a standard 240 volt power usage, but 230 volts and 115 are also fairly common. laptop power usage can vary between 15v and 20+v
it regulates +15v constant at output.
Yes you can. It will just take a little longer to complete the charge cycle.
V=i*r 18-15=3*r r=3/3=1 ohm
I'm assuming my multitester you mean multimeter. If that's true, then you've answered your own question. If you set the multimeter to a scale of 150 volts and you measure 82 volts, then the answer is 82 volts. The switch positions (15V, 150V) are there to help you measure voltage more accurately. They change the scale of the meter. For instance, if your meter has a gauge with 15 divisions on it (by gauge I mean the part where the needle moves) and you set the dial to 15 volts, then you now have 1 volt per division. In the same respect if you set it to 150 volts you now have 10 volts per division. So if it's set to 15 volts and you put 82 volts across it, the needle will sit all the way at the top. This just indicates that you've put too much voltage across it. Just keep changing the scale until you get to a point where the needle isn't all the way at the end of the scale. Then read how many volts per division you have, and read the voltage normally.
Almost certainly.
