Question

A student connected 4 resistors of 3 ohm each in parallel and experimentally measured the resistance of combination. What is the correct value of resistance?

Answer 1

As resistors are in parallel so

1/R=1/R1+1/R2........n terms

1/R=1/3+1/3+1/3+1/3

1/R=4/3

so R=3/4 ohms

Hope it helped!!

If helped mark it brainliest!!!
