Question

Draw a schematic diagram of circuit consisting of a battery of 1.5V and three resistances of 5 Ω, 4 Ω,3 Ω respectively joined in series with an ammeter and a key. Find out the current in the circuit.

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
