Ohm's Law — Quiz

Question 3 • Physical Science

A circuit has a current of 2 point 4 A The voltage is increased to 4 times its original value, while the resistance stays the same. How should the resistance change to return the current to its original value if the voltage remains at its increased amount?

Answer
A
It should increase to four times its value.
B
It should decrease to one-fourth of its value.
C
It should increase to two times its value.
D
It should decrease to one-half of its value.

Explanation

By Ohm’s law, current equals voltage divided by resistance. If the voltage becomes four times larger while resistance stays the same, the current also becomes four times larger. To bring the current back to its original value while keeping that increased voltage, resistance must also become four times its original value. So the correct choice is “It should increase to four times its value.”
