Question

What is the equivalent resistance of the parallel portion of the circuit?

Answer 1

Given:

Two resistors each of resistance R = 60 ohms are connected in parallel.

To find the equivalent resistance of the parallel portion.

Step-by-step explanation:

The equivalent resistance of the parallel circuit can be calculated by the formula

`(1)/(R_p)=(1)/(R1)+(1)/(R2)`

On substituting the values, the equivalent resistance of the parallel circuit will be

`\begin{gathered} (1)/(R_P)=(1)/(60)+(1)/(60) \\ =(2)/(60) \\ R_p=(60)/(2) \\ =30\text{ }\Omega \end{gathered}`

Thus, the equivalent resistance of the circuit is 30 ohms.
