A choke can be represented by a

A choke coil is simply a coil having a large inductance, but a small resistance. A device that can regulate the current in an A.C. circuit without much loss of energy is called as ‘choke coil’.

Four relations have been given. Select the correct relation?

The amount of flux produced by the magnet indicates the strength of the magnet. The more the magnetizing force (MMF), the more is the flux produced. The more the opposition to the flux path (i.e., reluctance or magnetic resistance) less is the flux produced. This relationship is expressed as

Flux = MMF/ Reluctance

Reluctance is the opposition offered by the material in the flux path to the establishment of the flux. The reluctance in a magnetic circuit is similar to the resistance in an electric circuit. Reluctance is the inverse of permeance.

MMF = Flux/Permeance

Four statements are given below. Identify the correct statement?

**Basic logic gates**: Basic logic gates are the building blocks of digital circuits that perform logical operations such as AND, OR, and NOT, on the binary inputs. Basic gates are mainly used in the fabrication of digital systems and are called integrated circuits (ICs).

**Derived logic gates**: Derived logic gates arc those logic gates that perform logical operations on the binary inputs with the help of two or more basic logic gates. A combination of AND, OR, and NOT are called derived gates. NAND, NOR, XOR, and XNOR are such a combination of AND, OR, and NOT gates.**Exclusive OR (XOR) Gate**

A gate that identifies the odd number of 1’s in the combination of the inputs is called the XOR gate. It is a functional combination of NOT, AND, and OR gates.
