Question

According to Ohm's law what would happen to the current if resistance was increased?
Increase
Decrease
Vary
Nothing

Answer 1

\[V=IR\]where V is voltage, I = current and R is resistance.

So if you increase R and keep V constant, what do you think will happen to I?

Answer 2

You can also rearrange it to get \[I=\frac{V}{R}\]...so if you increase R, what happens to I?

Answer 3

\[I\propto R^{-1}\]
