Answer:
1.Connecting wires provide a medium to an electrical current so that they can travel from one point on a circuit to another. In the case of computers, wires are embedded into circuit boards to carry pulses of electricity.
2. A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
3. An electromagnet is a coil of wire with an electric current flowing through it. When the wire is coiled around in a cylinder, we call this a solenoid. The solenoid becomes an electromagnet when a current flows through it.
4. When the switch is pressed and current flows through the circuit. The electromagnet is powered and generates a magnetic field that attracts the iron strip towards it. ... When the striking arm strikes the gong, the contact is broken and current stops flowing through the circuit.
Hope u understand the concept...
