Question

find the total current through the given circuit​

Answer 1

Answer:

1.9 A

Explanation:

first find the total resistance =

resistors 4 ohm 4 ohm and 8 ohm in series ( R= R1+R2+R3)

4+ 4+8 = 16 ohm

resistors 10 ohm 4 ohm  series ( R= R1+R2)

4+10 =14 ohm

resistors 2 ohm and 2 ohm series ( R= R1+R2)

2+2 = 4 ohm

now the total resistors are in parallel ( 1/R = 1/R1 + 1/R2 + 1/R3 )

1/16 + 1/14 + 1/4 =43/112

1/R = 43/112

now cross multiply

43R =112

R=112/43

=2.6 ohm

total resistance of circuit = 2.6 ohm

I=V/R

5/2.6

=1.9 A
