Question

If a current 12 Amps produce 480 Volts across a resistor how many votes would a current of 1.5 Amps produce across an identical resistor

Answer 1

Let us represent the voltage with V and the current with C.

If the two qantities are directly proportional to each other, we haeve that:

$\begin{gathered} V\propto C \\ \therefore \\ V=kC \end{gathered}$

where k is a constan
