# Electricity question about p.d. and resistance

## Recommended Posts

Hello everyone!

I have a short question pertaining to electricity.

I know that the potential difference across a component is directly proportional to the resistance. But does the current affect potential difference? What I mean is that, if the current were to increase, will the potential difference increase?

V=IR

So, yes, though normally the cause and effect are reversed — you raise the PD in order to increase the current.

If the resistance is fixed the only way to increase the current is to increase voltage.

Voltage is the pressure in the pipe system.Current is the amount of the flowing particle (may h2o) per unit time.Resistance is the diameter of the pipe.

Ohm's Law gives the current, voltage and Resistance relationships you are asking about.

I love the analogy of an electric circuit to a water pipe, emrekanca.
