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?
03A
0 0.4A
0 12A
G 3.6A

B. 0.4A

Explanation:

I've got that the answer is 0.4A. This is because current= voltage÷resitance

So, 1.2A=voltage÷resistance

However, if you only have 1/3 of the voltage AND the resistance remains constant, the current will change proportionally and will also decrease by 1/3 to give you 0.4A

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
