What happens to the total resistance in a parallel circuit if one of the resistors is removed?
Correct Answer: Total resistance increases.
- 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 a path for current. The more resistors there are, the easier it is for current to flow.
- Step 3: When you remove one resistor, you are taking away one of those paths for current.
- Step 4: With fewer paths available, the total current that can flow through the circuit decreases.
- Step 5: Since the total current decreases and the voltage remains the same, the total resistance of the circuit must increase.
- Step 6: Therefore, removing a resistor in a parallel circuit increases the total resistance.
