Ohm's Law - Technical MCQs

Q1:

The ___ rating of a resistor will increase with an increase in the surface area of the resistor.

A resistance

B current

C power

D voltage

ANS:C - power

R=L/A.
Increase of A, the R will be decreased.

Ohms law.
I=v/r.

Decrease in R the I and V will be increased.

Since P=IV.
the increase of both I and V it results to power increased.
