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

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%.

Q2. What is the process for entering single-phase voltage?
Ans. 
The process for entering single-phase voltage involves connecting the voltage source to the load through a single conductor.
• Connect the single-phase voltage source to the load through a single conductor

• Ensure proper insulation and grounding for safety

• Check the voltage level using a multimeter before connecting the load

• Make sure the load is compatible with the voltage rating
