Question

Calculate the equivalent resistance and the current through 10 ohm resistor in the following circuit​

Answer 1

Answer:

The equivalent resistance=20 ohm

Explanation:

R1=10 ohm, R2=20 ohm, R3=20 ohm

$\frac{1}{rp} = \frac{1}{r2} + \frac{1}{r3}$

$\frac{1}{rp} = \frac{1}{20} + \frac{1}{20}$

$\frac{1}{rp} = \frac{1 + 1}{20}$

$\frac{1}{rp} = \frac{2}{20}$

$\frac{1}{rp } = \frac{1}{10}$

$rp = 10 \: ohm$

$the \: equivalent \: resistance \\ = r1 + rp \\ = 10 + 10 \\ = 20 \: ohm$
