Q: In a series circuit, if one resistor fails open, what happens to the current in the circuit?
Solution: In a series circuit, if one resistor fails open, the current becomes zero because the circuit is broken.
Steps: 5
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: Identify what happens when a resistor fails open. 'Failing open' means that the resistor stops conducting electricity, creating a break in the circuit.
Step 3: Recognize that current is the flow of electricity. For current to flow, there must be a complete path.
Step 4: Since the resistor has failed open, the path is broken, and electricity cannot flow.
Step 5: Conclude that when the path is broken, the current in the circuit becomes zero.
