Explanation / Answer

here,

4 ohm , 2 ohm and 2 ohm are in parallel, let their equivalent resistance be R

1/R = 1/2 + 1/2 + 1/4

solving for R

R = 0.8 ohm

the current through 3 ohm , I1 = 6 /( R + 3)

I1 = 6 /( 3 + 0.8) A = 1.58 A

the current through 4 ohm , I2 = (V - I1 * 3) /4 = ( 6 - 1.58 * 3)/4 = 0.32 A

the current through 2 ohm , I3 = (V - I1 * 3) /2 = ( 6 - 1.58 * 3)/2 = 0.63 A

the current through 2 ohm , I4 = (V - I1 * 3) /2 = ( 6 - 1.58 * 3)/2 = 0.63 A

5)

the power delivered by battery , P = V * I1

P = 6 * 1.58 W = 9.48 W
