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

Answer»

LC of ammeter = 0.2/10a = 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
