Six dry cells each of e.m.f. 2.0 and internal resistance of 1.0(Omega) are connected in parallel across a load of 3.0(Omega). Calculate the effective current in the circuit.
-
A.
0.63A -
B.
0.50A -
C.
0.31A -
D.
0.22A
Correct Answer: Option A
Explanation
I = (frac{f}{n} = frac{1}{6 – 2})
I = (frac{v}{R + r} = frac{2}{3} + frac{1}{6} = 0.63)A
