Question

What is the equivalent resistance of the following network resistances

Answer 1

Answer:

The resistance of this imaginary resistor is the equivalent resistance of the circuit, Req R e q . There are two rules for finding equivalent resistance, for resistors in series and parallel. If several resistors are in series, we simply add up the resistances. Req=R1+R2+R3+...

Answer 2

Answer:

1\Rp=1/20+1/20

Rp=10

since two resistance are in parallel

one in series 10 ohm

so now in circuit 2 resistance of 10 ohm is present

so

Req=10+10=20ohm
