Resistors in Series and Parallel

• What is the equation for resistance?

  Resistance = potential difference / current
• How do you calculate current using potential difference and resistance?

  Divide potential difference by resistance
• What happens to resistors in series?

  They add together to form total resistance
• Why do resistors add in series?

  Current passes through each resistor sequentially
• What is a key fact about resistors in parallel?

  Total resistance is less than the smallest resistor
• Why does total resistance decrease in parallel circuits?

  More pathways for current to flow
• What happens to current in a parallel circuit compared to a series circuit?

  More total current flows in parallel
• What is equivalent resistance?

  Replacement of multiple resistors with one
