Question

A circuit has a current of 2 A. If the resistance in the circuit decreases to one-fourth of its original amount while the voltage

emains constant, what will be the resulting current?
0.5 A
2A
4A
BA

Answer 1

Answer:8a

Step-by-step explanation:

Answer 2

two ampheres

Step-by-step explanation:

the formula for calculating voltage is V=IR so if the current which is I is 2 and the resistance which is R is decreased to one forth then we will say

R=x multiplied by 1/4=x/4

V=2x/4 cross multiply then we have

since the voltage is constant then it is=1

so 4=2x divide both sides by 2 we then get 2 as our answer
