B) 9.4 watts | 9.4 वाट
O O
C)9.6 watts | 9.6 वाट​

Answer 1

Given :   an adjustable  resistor bears the following label 1.5 k ohms/  0.08A  

एडजस्टेबल रजिस्टर में  लेबल है  1.5 k ohms/  0.08A  

To Find :  rated power

रेटेड पावर

A)9.2 watts | 9.2 वाट

B) 9.4 watts | 9.4 वाट

C)9.6 watts | 9.6 वाट​

Solution:

rated power = I²R

I = 0.08 A

R = 1.5 kΩ = 1500 Ω

rated power = (0.08)² * 1500

= (64/10000) * 1500

=64 * 15 / 100

= 960/100

= 9.6

rated power = 9.6 watts

option C is correct
