Series and parallel resistor calculator
Connect three resistors in series or in parallel to a supply and see the total resistance, the current and how the voltage or current is shared.

Questions students ask
How do you add resistors in parallel?
1/R = 1/R₁ + 1/R₂ + 1/R₃. The total is always less than the smallest resistor.
What stays the same in a series circuit?
The current: the same current flows through every component, and the voltages add up to the supply.
