When resistors are connected in parallel, they are each on their own path. This means that electricity can run through any one of them at a time without flowing through the others.
The total current of the circuit is the sum of the current flowing through each resistor. (
Each resistor slows only a portion of the current.
This is different from when resistors are connected in series, where there is only one path for electricity to take through each resistor in order.
