Question

2. If the voltage is doubled and the resistance is not changed, what will happen to
the current in a resistive circuit?

Answer 1

Answer:

Remember Ohms law (the holy grail of electronics): V=IR

Explanation:

V=IR, where:

V=Voltage

I=Current

R=Resistance.

Looking at the equation (V=IR),

if R remains constant, but V is double, that means that the current has to also double, in order to keep the equation true.

Answer: the Current will double if voltage is doubled and resistance is kept constant.
