- Q1. What is ohm's law
- Ans.
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.
It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.
For example, if a circuit has a volt...

- Q1. 1/Wat ht vcb worck For Ht use
- Ans.
The question is asking about how a VCB (Vacuum Circuit Breaker) works for high voltage (HT) applications.
VCB is a type of circuit breaker that uses vacuum as the arc quenching medium.
It is commonly used in high voltage applications to interrupt or isolate electrical circuits.
When the VCB is closed, the contacts are in physical contact, allowing the current to flow.
When the VCB is opened, the contacts are separated, cre...

- Q1. Which is more deficult .AC&DC
- Ans.
AC and DC both have their own challenges, but AC is generally considered more difficult due to its changing voltage and frequency.
AC involves constantly changing voltage and frequency, which can be more challenging to work with compared to the steady flow of DC.
AC circuits require additional components like capacitors and inductors to manage voltage and current fluctuations.
DC circuits are simpler to understand and tro...

- Q1. Difference between single phase and three phase?
- Ans.
Single phase and three phase are two types of electrical power distribution systems.
Single phase has one live conductor and one neutral conductor, while three phase has three live conductors and one neutral conductor.
Single phase is commonly used in residential and small commercial applications, while three phase is used in industrial and large commercial applications.
Single phase power supply is suitable for low power...
- Q2. What is the difference between R phase, Y phase, B phase?
- Ans.
R, Y, B phases are the three phases of AC power supply. They differ in their phase angle and voltage level.
R phase has a phase angle of 0 degrees and is usually connected to the red wire.
Y phase has a phase angle of 120 degrees and is usually connected to the yellow wire.
B phase has a phase angle of 240 degrees and is usually connected to the blue wire.
The voltage level of each phase is the same, but they are out of ph...
- Q3. Voltage and current difference between Series and parallel of two or more batteries?
- Ans.
In series, voltage adds up while current remains the same. In parallel, voltage remains the same while current adds up.
In series, batteries are connected end-to-end, positive to negative. In parallel, batteries are connected positive to positive and negative to negative.
Series connection increases voltage but does not increase current. Parallel connection increases current but does not increase voltage.

- Q4. What are the steps to maintain the battery in periodically?
- Ans.
Periodic maintenance of batteries is crucial for their longevity and optimal performance.
Check the battery terminals for corrosion and clean them if necessary
Inspect the battery case for any cracks or damage
Ensure that the battery is securely fastened in place
Check the electrolyte level and top up with distilled water if required
Test the battery voltage and recharge if necessary
- Q5. How to find in a faulty battery?
- Ans.
A faulty battery can be identified by checking its voltage, capacity, and physical appearance.
Check the voltage of the battery using a multimeter
Test the capacity of the battery using a battery tester
Inspect the physical appearance of the battery for any signs of damage or leakage
Check the battery terminals for corrosion or loose connections
Compare the battery's performance to its specifications
- Q6. What is the difference FUSE, MCB, ELCB, RCCB?
- Ans.
FUSE, MCB, ELCB, and RCCB are all electrical protection devices, but they differ in their functions and applications.
FUSE is a simple device that protects electrical circuits from overloading or short-circuiting by melting and breaking the circuit.
MCB (Miniature Circuit Breaker) is an automatic switch that trips and cuts off the power supply when there is an overload or short-circuit.
ELCB (Earth Leakage Circuit Breaker...
- Q7. Draw the diagram of DOL starter.
- Ans.
A DOL starter is a direct online motor starter that provides full voltage to the motor.
Consists of a contactor, overload relay, and start/stop buttons
The contactor connects the motor to the power supply
The overload relay protects the motor from overloading
The start/stop buttons control the on/off function of the motor
Used for small motors with low starting current
Not suitable for large motors or motors with high starti
