Question

A resistor of 10 ohm is considering parallel with another resistor of ‘X’ohm .
The resultant resistance of the combination is found to be 3.75 ohm.
What is the value of ‘X’?

Answer 1

Answer:

Explanation:as they are in parallel so apply formula 1/req=1/r1+1/r2+....

So 1/3.75=1/10+1/x

Now solve for x
