- Q1. What is the current and voltage difference?
- Ans.
Current is the flow of electric charge, measured in Amperes, while voltage is the force that drives the current, measured in Volts.
Current is the rate of flow of electric charge in a circuit
Voltage is the electrical potential difference that drives the current
Current is measured in Amperes (A)
Voltage is measured in Volts (V)
Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance
- Q2. Types of motor ?
- Ans.
Types of motors include AC motors, DC motors, synchronous motors, asynchronous motors, stepper motors, and servo motors.
AC motors: Alternating current motors commonly used in household appliances and industrial applications.
DC motors: Direct current motors used in applications where speed control is important.
Synchronous motors: Maintain a constant speed and are used in applications like clocks and timers.
Asynchronous ...
- Q3. AC or DC different?
- Ans.
AC and DC are two types of electrical current with different characteristics and applications.
AC stands for alternating current, which periodically changes direction and magnitude.
DC stands for direct current, which flows in one direction at a constant voltage.
AC is commonly used in household appliances and power distribution systems.
DC is often used in electronics, such as batteries and computer power supplies.

- Q1. What is slip ring
- Ans.
A slip ring is an electrical component used to transfer power and electrical signals from a stationary to a rotating structure.
Allows for continuous rotation without tangling wires
Commonly used in electromechanical systems like motors, generators, and wind turbines
Consists of stationary brushes and rotating conductive rings
Helps in transmitting power, data, and signals across rotating interfaces
- Q2. What is oer unit slip
- Ans.
Unit slip is the difference between synchronous speed and rotor speed in an induction motor.
Unit slip is expressed as a fraction or percentage.
It is used to calculate the rotor speed of an induction motor.
Unit slip is necessary for determining the torque and efficiency of the motor.
For example, if the synchronous speed of a motor is 1800 RPM and the rotor speed is 1750 RPM, the unit slip would be 0.0278 or 2.78%.
