What would happen to the total current if you added another resistor in parallel and kept
the power supply at 15 V? Would it increase, decrease or stay the same ?
Suppose you have a parallel circuit with a fixed voltage. When you add more resistors in
parallel, what happens to a) the current? b) the total resistanance?
Answered by oobleck
a resistor in parallel provides another path for the current, so the total current will increase.
So, what do you think that means for the total resistance?
Answered by henry2,
a. The current will increase.
b. Decrease to a value less than either resistor:
R = R1*R2/(R1+R2).
