A fuse can be a saviour against:
Correct answer: B. High current
- A. High voltage
- B. High current
- C. High power
- D. Heating of wires
Explanation
To protect a high-voltage circuit, you need a properly rated fuse. Here are five popular examples for consideration in your next design. A fuse is simple in concept: Current flows through a thin metal wire, and when that current gets too high, the metal heats and melts, breaking the circuit.

About Steady Current
Steady current is the continuous flow of charge at a constant rate through a conductor. The topic covers current, charge, potential difference, resistance, Ohm's law, resistivity and electrical power, along with series and parallel circuits, while distinguishing conventional current direction from electron motion.
