Ohm's Law — Quiz

Question 18 • Physical Science

If voltage in a circuit is constant, the current can be cut to half of its original value by changing the resistance to ________ its original value. Which best completes the statement?

Answer
A
four times
B
one-half
C
one-fourth
D
two times

Explanation

Ohm’s law is I = V/R. With voltage held constant, current varies inversely with resistance, so doubling the resistance cuts the current in half. The correct choice is “two times.”
