Question

A circuit has a current of 1.2 A. If the voltage decreases to one-third of its original amount while the resistance remains constant, what will be the resulting current?

Answer 1

b

Step-by-step explanation:

Answer 2

Consider the formula ...

Current = (voltage) / (resistance) .

If the resistance doesn't change, then the current is
directly proportional to the voltage.

If the voltage decreases to 1/3 of what it used to be,
then the current does the same thing.

1.2 A ----> 0.4 A
