Q1. How many types of gates? ,And its truth tables
Ans. 
There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR.
• AND gate: output is high only if all inputs are high

• OR gate: output is high if any input is high

• NOT gate: output is the inverse of the input

• NAND gate: output is low only if all inputs are high

• NOR gate: output is low if any input is high

• XOR gate: output is high if inputs are different

• XNOR gate: output is high if inputs are the same

Q1. Circuit diagram for half wave
Ans. 
A half wave circuit diagram shows the flow of current in a circuit during half of the input cycle.
• A half wave rectifier circuit consists of a diode, a resistor, and a load.

• During the positive half cycle of the input signal, the diode conducts and allows current to flow through the load.

• During the negative half cycle, the diode blocks the current flow.

• The output waveform of a half wave rectifier is a pulsating DC wavefo...read more

Q1. What is transforme What is bush What is relay What is buck Other
Ans. 
Transformers, bushings, relays, and buck converters are all electrical components used in power systems.
• Transformers are devices that transfer electrical energy from one circuit to another through electromagnetic induction.

• Bushings are insulating structures that allow electrical conductors to pass through walls or barriers without allowing current to leak.

• Relays are switches that are operated electrically and used to c...read more

Q2. What is transformer.
Ans. 
A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction.
• Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.

• They consist of two coils of wire, known as the primary and secondary coils, which are wrapped around a magnetic core.

• When an AC voltage is applied to the primary coil, it creates a magne...read more

Q1. What is reactor transformer?
Ans. 
A reactor transformer is a type of transformer used in power systems to control voltage and current levels.
• It is used to regulate voltage and current levels in power systems.

• It is designed to handle high levels of current and voltage fluctuations.

• It is often used in conjunction with other types of transformers to provide optimal power distribution.

• Examples include step-up and step-down reactors, which increase or decre

Q1. Hall sensor working principle?
Ans. 
Hall sensor detects magnetic field and converts it into a voltage signal.
• Hall sensor is a transducer that detects the presence of a magnetic field.

• It works on the principle of the Hall effect, where a voltage is generated across a conductor when a magnetic field is applied perpendicular to the current flow.

• The voltage generated is proportional to the strength of the magnetic field.

• Hall sensors are used in various appli...read more
