Question

Answer the question, i have send a attachment with it​

Answer 1

Answer:

8

Explanation:

r2+r3=6

1/r4+1/6=

1/Req=1/3+1/6=1/2

Req=2

Req+r1+r5=8

hence

Req(total circuit)=8

Answer 2

Answer:

8 Ω

Explanation:

R2, R3 and R4 are in parallel series so we need to find Rx

            We firstly add R2 and R3 which are in series R2+R3=3+3=6 Ω and call     it Ry

            Then we have R4 and Ry in parallel so we need to find 1/Rx=1/R4+1/Ry

1/Rx=1/3+1/6 so Rx=2 Ω

All it is left is the series R1+Rx+R5=3+2+3=8Ω
