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
correct option: b
1/R = 1/4 + 1/4 + 1/4 = 3/4
R = 4/3
I = V/R
= 12 A
R = 4/3
I = V/R
| = | 16 |
| 4/3 |
| = | 16 x 3 |
| _4 |
= 12 A
