Question

A 2 w carbon resistor is color coded with green, black, red and brown respectively. The maximum current which can be passed through this resistor is :

Answer 1

The maximum of resistors be 2n/ lx,

Answer 2

answer is 20 ma.

p= 2 w

resistance we get is 50 × 10 ^2.

therefore

we know that

p=i^2 r

so, I=√p/r

we get,

I=√ 2/50×10^2

on solving we get,

I= 20 ma.
