Q: In a parallel circuit, if one resistor fails, what happens to the total resistance? (2020)
Solution: In a parallel circuit, if one resistor fails, the total resistance decreases because there are fewer paths for current to flow.
Steps: 5
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. If one resistor fails, it means that one path is no longer available.
Step 3: Realize that when one path is removed, the total number of paths for current decreases.
Step 4: Remember that in a parallel circuit, having more paths (resistors) actually lowers the total resistance. So, if one path is removed, the total resistance increases.
Step 5: Conclude that if one resistor fails, the total resistance of the circuit increases because there are fewer paths for current to flow.
