Physics for IGCSE & O level - Electricity (Section 12 - No. 8)
In a parallel circuit, which of the following is true?
The voltage is the same across each branch.
The current is the same through each branch.
The total current is the sum of the branch currents.
The resistance of the branches are added together to determine the total resistance.

In parallel, the voltage is the same, and the currents add up. Resistance is calculated differently.
