Question

A resistor of 2.6Ω is connected in series with a parallel combination of 4Ω and 6Ω resistors. If the power consumed in 4Ω resistor is 36 watts, find, Voltage across different resistors, Source Voltage & Source Current.

Answer 1

Explanation:

(a) V= 6V

Req = 1/R1 + 1 /R2 = 1/4 + 1/6 = 5/12 = 12/5 ohm = 2.4 ohm

According to ohm's law ,

V = IR

I = V/R

I = 6/2.4

I = 2.5 A

(b) 1) V = 6 V , R= 6 ohm , I = ?

I = V/R

I = 6/6

I = 1 A

2) V = 6V , R = 4 ohm , I = ?

I = V/R

I = 6 /4

I = 1.5 A
