Question

The current flowing through a resistor connected in an electrical circuit and the potential difference developed across its ends are shown in the given ammeter and voltmeter. Find the least count of the voltmeter and ammeter .What is the voltage and the current across the given resistor? 2
27

Answer 1

Answer:

LC of ammeter = 0.2/10 A = 0.02 A

LC of Voltmeter = 1/10 = 0.1 V

Current = 15 x 0.02 A = 0.3 A

Potential difference = 21 x 0.1 V = 2.1 V
