Question

R1= 6 ohm, R2= 8ohm , R3 = 4ohm , R4= 12ohm..
find the answer!

Answer 1

Total resistance=12 ohm.

Current flowing through the circuit=1A.

Answer 2

1) add as series ( R2+R3 = R5 )

2) add as parallel ( R5+R4 =R6 )

3) simply add ( R6 + R1 = total resitance ) as series

Solution

R5 = 12

R6 = 6 (1/R6=1/12+1/12=2/12=1/6)

T.R= 6+6 =12 ohm
