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.
15v appliances
somehow
-7
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
11-15v from batt.
Almost certainly.
