ELLIE: And on the other hand, a parallel circuit has electrical components on separate branches, so the electrons can take different routes around the circuit. JAMES: And if you want to know ...

The National Electrical Code (NEC) sets out specific requirements. Though our homes have 15-amp and 20-amp branch circuits ...

The current through them will be different if they have different resistances. The total current in the circuit is the sum of the currents through each branch.
