Question

A circuit provides a current of 20A at an operating voltage of 120v how many 75w bulbs can operate with this voltage source

Answer 1

Hey buddy here is ur solution !!

I = 20A
V = 120 V
P = 75 W

P = V × I

Also , R = V^2 /P

R = ( 120 )^2 / 75

R = 192

Maximum volt = 120 V

Maximum current = 20 A

R1 = V/A

R1 = 120 /20

R1 = 6

Now ,

R1 = r/n

6 = 192 /n

n = 32 .
