The circuit shown in the Figure contains two batteries, with an emf V 1 = 17, V

Question

The circuit shown in the Figure contains two batteries, with an emf V1 = 17, V2 = 3, and an internal resistances r1 = 0.6, r2 = 1.2, and two resistors R1 = 3.2, R2 = 5.8, respectively. Find the current in the circuit.

Express the answer with two decimal places

The circuit shown in the Figure contains two batteries, with an emf V1 = 17, V2 = 3, and an internal resistances r1 = 0.6, r2 = 1.2, and two resistors R1 = 3.2, R2 = 5.8, respectively. Find the current in the circuit. Express the answer with two decimal places

Explanation / Answer

(17 - 3) = net PD of 14V.
Total circuit resistance = (3.2 + 5.8 + 0.6 + 1.2) = 10.8 ohms.
Circuit current = (E/R), = 14/10.8, = 1.296A.
