An alternating current is supplied to an electronic component with a rating that the voltage across it can never, even for an instant, exceed 16 v. what is the highest rms voltage that can be supplied to this component while staying below the voltage limit?
a)8 sqrt 2 v

b) 16 sqrt 2 v

c) 256 v

d) 8

A)

Explanation:

Maximum voltage =

Maximum voltage and rms voltage are related to each other by

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
