Question

The current flowing through a resistor connected in a circuiy and the potential difference developed across its ends are as shown in the diagram by milliammeter and voltmeter readings respectively a) what is the least counts for these meters b) what is the resistance of hte resistor​

Answer 1

1. 10mA and 0.1V

2. 9.6 ohm

Answer 2

Answer:

LC of ammeter =  0.2 / 10

= > 0.02 A

A = 0.02 A

LC of Voltmeter =  1 / 10

= > 0.1 V

V = 0.1 V

Current = 15 x 0.02 A = 0.3 A

Potential difference = 21 x 0.1 V = 2.1 V
