The circuit shown in the Figure contains two batteries, with an emf V 1 = 11, V

Question

The circuit shown in the Figure contains two batteries, with an emf V1 = 11, V2 = 3, and an internal resistances r1 = 2.2, r2 = 1.9, and two resistors R1 = 3.3, R2 = 5.6, respectively. Find the current in the circuit. Express the answer with two decimal places.

Explanation / Answer

using kirchoffs loop rule in anti clockwise

11 - i 2.2 - 3.3 i - 1.9 i - 3 -5.6i = 0

8= 13 i

i = 0.615385 A
