- Q1. Difference between rccb & mcb
- Ans.
RCCB and MCB are both electrical protection devices, but they differ in their functionality and applications.
RCCB stands for Residual Current Circuit Breaker, while MCB stands for Miniature Circuit Breaker.
RCCB is designed to protect against electrical leakage and ground faults, while MCB is primarily used for overcurrent protection.
RCCB detects the imbalance in current between the live and neutral wires, while MCB det...
- Q2. Circuit diagram of motor starter
- Ans.
A motor starter circuit diagram is used to start and stop an electric motor.
Motor starters typically consist of a contactor, overload relay, and start/stop buttons.
The contactor is used to switch the motor on and off.
The overload relay protects the motor from overheating.
The start/stop buttons are used to control the motor.
The circuit diagram shows the connections between these components.

(6 Questions)
- Q1. Define the term electrical engineering
- Ans.
Electrical engineering is a field of engineering that deals with the study and application of electricity, electronics, and electromagnetism.
Involves designing, developing, testing, and supervising the production of electrical equipment and systems
Includes working with power generation, transmission, distribution, and utilization
Incorporates knowledge of electronics, electromagnetism, and computer systems
Applies princi...
- Q2. Define the principle of motor
- Ans.
The principle of motor involves converting electrical energy into mechanical energy to produce motion.
Motors operate based on the principle of electromagnetic induction
Electric current flowing through a wire in a magnetic field creates a force that causes the wire to move
This movement is harnessed to produce mechanical energy and drive motion
Examples include DC motors, AC motors, and stepper motors
- Q3. What is an electric shock
- Ans.
An electric shock is a sudden discharge of electricity through a person's body, causing injury or even death.
An electric shock occurs when a person comes into contact with a source of electricity.
The severity of an electric shock depends on the voltage, current, and duration of exposure.
Symptoms of an electric shock can range from mild tingling to muscle contractions and burns.
Examples of sources of electric shock incl...
- Q4. How can one protect themselves from an electric shock
- Ans.
To protect oneself from an electric shock, one should follow safety precautions and use proper equipment.
Always turn off the power source before working on electrical equipment
Use insulated tools and wear rubber gloves when working with live wires
Avoid working in wet conditions or with wet hands
Install Ground Fault Circuit Interrupters (GFCIs) in areas where water is present
Regularly inspect and maintain electrical equ...
- Q5. What will resistance connected to a source voltage in series do
- Ans.
Resistance connected to a source voltage in series will affect the current flowing through the circuit.
Increases the total resistance in the circuit
Decreases the total current flowing through the circuit
Causes a voltage drop across the resistor
Can be calculated using Ohm's Law: V = I * R
- Q6. Define ohm's low
- Ans.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
Ohm's law is represented by the formula: V = I * R, where V is the voltage, I is the current, and R is the resistance.
It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.
Ohm's law is...
