"Current in Parallel Circuits

• What is meant by a parallel circuit?

  A parallel circuit is a circuit that contains branches.
• How does current flow in a parallel circuit?

  The current splits among the branches in a parallel circuit.
• What is the direction of conventional current flow?

  Conventional current flows from the positive end to the negative end of the cell.
• How is current measured in a circuit?

  Current is measured using an ammeter.
• What characterizes a series circuit?

  A series circuit has only one path for current to flow.
• What happens to the current in a series circuit?

  The current is the same all the way around a series circuit.
• What is the current leaving the cell in the example given?

  The current leaving the cell is 0.3 amp.
• How does the current split in the branches of a parallel circuit?

  Some of the current passes through both branches in a parallel circuit.
• What are the currents in the upper and lower branches in the example?

  The upper branch has a current of 0.1 amp and the lower branch has a current of 0.2 amp.
• What is a key fact about parallel circuits regarding current?

  The current in the branches adds up to the total current leaving the cell.
• If the current leaving the cell is 0.5 amp and the current in the upper branch is 0.3 amp, what is the current in the lower branch?

  The current in the lower branch is 0.2 amp.
• If the current in the upper branch is 0.4 amp and the current in the lower branch is 0.3 amp, what is the total current leaving the cell?

  The total current leaving the cell is 0.7 amp.
• What are the characteristics of a parallel circuit?

  • Contains branches
  • Current splits among branches
  • Total current is the sum of currents in branches
• What is the relationship between current in branches and total current in a parallel circuit?

  • The current in the branches adds up to the total current leaving the cell.
• What will be covered in the later video regarding parallel circuits?

  • Factors determining how much current moves through different branches.
