Quiz Questions Over Electrical Force

EMF stands for Electro Motive Force. It refers to the voltage or electrical potential difference that is generated by a source such as a battery or a generator. This force drives the flow of electric current in a circuit. EMF is measured in volts and represents the energy per unit charge provided by the source. It is important in understanding and analyzing electrical circuits and devices.

The given answer, "Dong Tester," is not an electrical tester. This is because there is no such device or tool called a "Dong Tester" in the field of electrical testing. The other options listed, such as Volt Meter, Tong Tester, and Ammeter, are all commonly used electrical testers that measure different aspects of electrical circuits. However, the term "Dong Tester" does not exist and is likely a made-up or incorrect option.

Electromotive force (EMF) refers to the potential difference or voltage generated by a source such as a battery or a generator. Heat, magnetic, and chemical are all forms of energy that can generate an EMF. However, radiation does not generate an EMF. Radiation refers to the emission of energy as electromagnetic waves or as moving subatomic particles, but it does not produce a voltage or potential difference.

When a cell is charging, the process of electrolysis occurs, which involves the decomposition of water into its constituent elements, hydrogen and oxygen. As a result, hydrogen gas is given off as a byproduct during the charging process.

Green is not used for emergency cables because it is commonly associated with safety and is often used to indicate that equipment or materials are safe to use. Red, white, and orange are commonly used for emergency cables to indicate danger, caution, or warning.

The term 'MIMS' stands for Mineral Insulated Metallic Sheathed. This refers to a type of electrical cable that consists of a mineral insulation material surrounding a metallic sheath. This type of cable is commonly used in high-temperature and hazardous environments due to its excellent fire resistance and insulation properties.

The T.C.N.S is not a type of Earthing System. The T.T, T.N.S, and T.N.C.S are all valid types of Earthing Systems.

The correct answer is "External earth loop independence." This refers to the ability of a system or device to operate without being affected by any interference or disturbances caused by the grounding or earthing system. It means that the system or device can function independently without any negative impact from the earth loop.

The correct answer is "Supply cable - cut out unit - meter - main switch - consumer unit". This sequence is logical and follows the typical order of electrical components in a circuit. The supply cable brings electricity from the source to the cut out unit, which acts as a safety measure. The meter measures the amount of electricity consumed. The main switch controls the flow of electricity to the consumer unit, which distributes it to various circuits in the building.
