Current in Parallel Circuits

• What is a parallel circuit?

  A circuit with branches for current flow
• How does current flow in a parallel circuit?

  The current splits among the branches
• What is the direction of conventional current flow?

  From positive to negative terminal
• How is current measured in a circuit?

  Using an ammeter placed in the circuit
• What does a parallel circuit contain?

  Branches where current can split
• What is the key fact about current in parallel circuits?

  The current in branches adds to total current
• What determines how much current moves through different branches of a parallel circuit?

  • Resistance in each branch
  • Voltage across the branches
  • Total current supplied by the source
