- 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.

- 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
