Q17. Which component is designed to protect electrical equipment from damage caused by overload or short circuit?

Transfer Switch

Stabiliser

Transient

Circuit Breaker

Explanation
A circuit breaker is a device designed to protect electrical equipment from damage caused by overload or short circuit. Circuit breakers are designed to detect when too much current is flowing through a circuit and to shut the circuit off when that happens. This protects the equipment from damage due to overloading or short circuiting, and it also helps prevent fires and other accidents.

Q18. For which one of these processes is Direct Current essential, and will not work with alternating current?

Heating

Lighting

Turning a motor

Electrolysis

Explanation
Direct Current (DC) is essential for the process of electrolysis. Electrolysis is the process of breaking down a compound using an electric current. The electric current causes ions to move, which results in a chemical reaction that breaks down the compound. In order for electrolysis to work, a direct current is required, as the ions must flow in one direction. Alternating Current (AC) changes direction and would not provide a consistent flow of ions.
Heating, lighting, and turning a motor can be done by either DC or AC. Heating can be done by passing an electric current through a heating element, which can be powered by either DC or AC. Lighting can be done by passing an electric current through a light bulb, which can be powered by either DC or AC. A motor can be powered by either DC or AC, but the type of motor and the application will determine which type of current is more suitable.

Q19. True or False: A grounded wire is connected to metal appliance cases

True

False

Explanation
A grounded wire is connected to metal appliance cases in order to provide a safe path for electricity to flow in the event of a short circuit or other electrical problem. This helps to protect the appliance and the people using it from potential electrical shocks, and it also helps prevent fires and other accidents.

Propane or natural gas generators may also be used, depending on the availability of fuel sources.

Q27. AC is more easily distributed than DC. This is because:

AC can be transmitted using lighter wires.

DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.

AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.

Wires have less resistance if they are carrying AC

Explanation
AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don’t need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.
