Parallel Circuits - Current
Physics: Cambridge International GCSE Supplement, topic 4.8.7
Current in Parallel Circuits
In a parallel circuit the current through the energy source is equal to the sum of (adding up all of) the currents in the separate branches.
Water pipes
- Imagine a water flowing through a pipe that splits into two.
- The amount of water flowing in the two pipes must add up to the amount of water in the single pipe, as no water leaks out or disappears.
