Question

a circuit consists of a battery made u[ of 5 cells each of 2v and a 20 ohm resistor. calculate the current flowing thorugh the 20 ohm resistor

Answer 1

Answer:

10 V Battery ; Rest Components  

Equivalent resistance = R1 +R2 +R3

                                         = 5 + 10 + 15  

                                         = 30 Ω

Current in the circuit , I = V / R  

                           

(ii) Potential Differences across 5Ω  resistor , V = IR
