Questions & Step-by-Step Solutions

In a parallel circuit, if one resistor is removed, what happens to the total resistance?
  • Step 1: Understand what a parallel circuit is. In a parallel circuit, there are multiple paths for electricity to flow.
  • Step 2: Know that each resistor in a parallel circuit provides an additional path for the current.
  • Step 3: Realize that when you have more paths (resistors), the total resistance is lower.
  • Step 4: If you remove one resistor, you are taking away one of those paths.
  • Step 5: With fewer paths for the current to flow, the total resistance of the circuit increases.
  • Step 6: Therefore, removing a resistor in a parallel circuit decreases the total resistance.
