How do i calculate a parallel circuit

I need help learning how to calculate the total resistance and total current flow on a parallel circuit, I need someone to explain it to me and help me out. Thanks

Well as you might now V= IR or simply put voltage equals current multiplied by resistance. Now to figure out the total resistance you need to move then R onto the other side of the equation. The V always stays on top so the equation to find the total resistance in a circuit would R = V divided by I
To find the total current in a circuit you have to move the I to the other side of the equation so it the equation to find the total current would be I = V divided by R

Voltage = V Measured in volts
Current = I Measured in amps
Resistance = R. Measures in ohms

Hope this helps :)

Hi John,

It may be a little hard starting off with the attached source but I think it will help you understabd and solve simple resistive parallel circuits.

Hope this helps,

You learn it better through doing an actual example.
