Questions & Step-by-Step Solutions

Which device is used to protect electrical equipment from overcurrent?
  • Step 1: Understand what overcurrent means. Overcurrent is when too much electrical current flows through a circuit.
  • Step 2: Learn about fuses. A fuse is a small device that is part of an electrical circuit.
  • Step 3: Know the function of a fuse. When the current exceeds a safe level, the fuse melts.
  • Step 4: Recognize the result of a melted fuse. When the fuse melts, it breaks the circuit, stopping the flow of electricity.
  • Step 5: Conclude that fuses protect electrical equipment from damage caused by overcurrent.
