Questions & Step-by-Step Solutions

In a series circuit, if one resistor fails, what happens to the current in the circuit? (2019)
  • Step 1: Understand what a series circuit is. In a series circuit, all components are connected one after the other in a single path.
  • Step 2: Know that current is the flow of electricity through the circuit.
  • Step 3: Realize that if one resistor in the series circuit fails (like if it breaks or is removed), it creates a gap in the circuit.
  • Step 4: Understand that when there is a gap in the circuit, the electricity cannot flow through it.
  • Step 5: Conclude that because the electricity cannot flow, the current in the circuit stops completely.
