Parallel currents and their practical implications

Electricity and circuits • Series and parallel circuits

Key concepts

What you'll likely be quizzed about

  • Parallel currents occur when two or more paths are available for electric charge to flow.
  • In a parallel circuit, the potential difference across each pathway is the same, but the current may vary depending on the resistance of each branch.
  • The total current supplied by the source is the sum of the currents flowing through each branch.

What happens if one branch in a parallel circuit fails?

Click to reveal answer

If one branch fails, current can still flow through the other branches, keeping other devices operational.

Key notes

Important points to keep in mind

Ensure all appliances receive equal voltage in parallel circuits.

Adding branches lowers total resistance.

Failures in one branch do not affect others.

Use Ohm's Law to analyze individual branches.

Total current is the sum of branch currents.
