Question

Two resistors of 10 and 15 n are connected. What is their combined resistance if they are connected: a) in series b) in parallel?​

Answer 1

Step-by-step explanation:

Given that,

Two resistors of 10 ohms and 15 ohms are connected.

In series combination, the equivalent resistance is given by :

`R_s=R_1+R_2\\\\R_s=10+15\\\\R_s=25\ \Omega`

In parallel combination, the equivalent resistance is given by :

`(1)/(R_p)=(1)/(R_1)+(1)/(R_2)\\\\(1)/(R_p)=(1)/(10)+(1)/(15)\\\\R_p=6\ \Omega`

Hence, this is the required solution.
