In a series circuit, if one resistor fails (opens), what happens to the current in the circuit?
Correct Answer: Current becomes zero.
- Step 1: Understand what a series circuit is. In a series circuit, all components are connected one after another in a single path.
- Step 2: Know that current is the flow of electricity through the circuit.
- Step 3: Recognize that if one resistor in the series circuit fails (opens), it creates a break in the circuit.
- Step 4: Realize that when there is a break in the circuit, electricity cannot flow through it.
- Step 5: Conclude that since the electricity cannot flow, the current in the circuit becomes zero.
