Question

Assume that you have a parallel circuit with forty-eight, 1,000 ohm lights connected to a 120 volt source. The total current flow (in amps) through the circuit is approximately: cannot be determined based on the information provided 3 3 6 120 2.5 .

Answer 1

5.77 A

Step-by-step explanation:

The formula for resistors in parallel combination is 1/R = 1/R1 + 1/R2 + 1/R3 +..

Since there are 48 resistors connected in parallel, the total resistance of the parallel combination is

1/1000 + 1/1000 + ... 48 times

so total resistance 1/R = 48/1000

Therefore R = 1000/48 = 20.8333..

R = 20.8 ohm

Now using the formula V = IR

V = 120, R = 20.8 ohm

I = V/R = 120/20.8 = 5.77 A
