Question

Q. The current flowing through a resistor connected in an electrical circuit and the potential difference
developed across its ends are shown in the given diagrams


The value of resistance of the resistor in ohms is

25

20

15

10

Answer 1

Explanation:

the value of resistant in resister is 15 ohms

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
