If you double the voltage in a circuit and reduce the resistance by a factor of four, what will happen to the current?

a.) it will double

b.) it will decrease by factor of 2

c.) it will increase by a factor of 8

c.) it will decrease by a factor of 8

doubling or tripling the voltage will cause the current to be doubled or tripled. On the other hand, any alteration in the resistance will result in the opposite or inverse alteration of the current. So doubling or tripling the resistance will cause the current to be one-half or one-third the original value.
