Answer:
Step-by-step explanation:Draw a circuit diagram for a circuit consisting of a battery of five cells of 2 volts each, a 5 Ω resistor, a 10 Ω resistor and a 15 Ω resistor, an ammeter and a plug key; all connected in series.
Draw a circuit diagram for a circuit consisting of a battery of five cells of 2 volts each, a 5 Ω resistor, a 10 Ω resistor and a 15 Ω resistor, an ammeter and a plug key; all connected in series. Also connect a voltmeter to record the potential difference across the 15 Ω resistor and calculate :
(i) the electric current passing through the above circuit and
(ii) potential difference across 50 resistor when the key is closed.

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
