Three 4Ω resistors connected in parallel have a potential difference of 16 V applied across them. What is the total current in the circuit?
A
14 A
B
12 A
C
10 A
D
8 A
Verified Correct Answer: B.
Physical Principles & Numerical Solution
1/R = 1/4 + 1/4 + 1/4 = 3/4
R = 4/3
I = V/R
= 164/3
= 16 x 3_4
= 12 A
