Series and Parallel Circuits

• What is the current behavior in a series circuit?

  Current is the same everywhere
• What happens to total resistance when a resistor is added in series?

  Total resistance increases
• What is the total current behavior in a parallel circuit?

  Total current is the sum of branch currents
• What is the potential difference across each branch in a parallel circuit?

  It is the same as the source potential difference
• What is the total resistance of resistors in parallel compared to the smallest resistor?

  Total resistance is less than the smallest resistor
• What happens to total resistance when a resistor is added in parallel?

  Total resistance decreases
