Question

According to ohms law if you don't change the value of the resistor and you double the voltage in a circuit the amount of current flowing will _______.

A. Be multiplied by the amount of resistance
B. Remain the same also
C. Divide it in half
D. Double

Answer 1

Answer: D (doubled)

According to ohm's law

I = V/R ,

V = IR ; R = constant and V is doubled

From the equation

V is directly proportional to the current, and it is given that R is constant ;

2V = 2I. R since R = constant

Hence I is doubled.
