Question

A circuit has a current of 2.4 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?

It should decrease to one-half of its value.
It should decrease to one-fourth of its value.
It should increase to two times its value.
It should increase to four times its value.

Answer 1

It should increase to four times it's value.

Step-by-step explanation:

This is because current goes up with voltage (which is a positive correlation). And for the current to not be over used or over work the load you work slow it down by multiplying the resistance to what it would be if it had a reaction to the voltage increasing.
