What is the device to protect equipments from the electric shock?
Detailed Explanation:
Fuse is a safety device containing a thin wire with low melting point that melts and breaks the circuit when excess current flows, protecting equipment from electric shock, overload, and short circuits.
Generator produces electricity, Motor converts electrical to mechanical energy, and Current controller regulates current but does not automatically disconnect during faults—only the fuse provides automatic protection.
Which of the following is the resistance of the wire?
Detailed Explanation:
Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) as V = IR.
Rearranging this formula gives R = V/I, which is the standard definition of resistance in ohms (Ω).
