Answer 1

Answer #1

Here ,

for R1 and 10 Ohm in series

R2 = 10 + 38

R2 = 48 Ohm

R2 , 40 Ohm and 30 Ohm are in parallel

1/R3 = 1/48 + 1/30 + 1/40

solving for R3

R3 = 12.63 Ohm

for R3 and 50 Ohm in series

Req = 12.63 + 50

Req = 62.6 Ohm

the equivalent of the circuit resistances is 62.6 Ohm
