A.C to D.C. conversion can be done using a rectifier circuit.
A rectifier circuit can be used to convert A.C. to D.C.
The rectifier circuit can be half-wave or full-wave.
Half-wave rectifier only allows half of the A.C. wave to pass through, while full-wave rectifier allows the entire wave.
The rectifier circuit can be made using diodes.
The output of the rectifier circuit is not smooth and requires filtering using capacito...
The question is unclear and needs clarification.
The question needs to be rephrased or clarified.
It is unclear what is meant by 'tips of electrical cables'.
More information is needed to provide an accurate answer.
The question is asking for 3 types of something related to the job of Electrical Supervisor.
Provide 3 types of electrical equipment
Provide 3 types of electrical systems
Provide 3 types of electrical hazards
There are two types of conductors: electrical and thermal.
There are two types of conductors: electrical and thermal.
Electrical conductors allow electricity to flow through them easily, while thermal conductors allow heat to flow through them easily.
Examples of electrical conductors include copper, aluminum, and gold.
Examples of thermal conductors include metals like copper and aluminum, as well as non-metals like diamo
I applied via Recruitment Consultant and was interviewed in Oct 2020. There was 1 interview round.

I applied via Referral and was interviewed before Jul 2020. There were 3 interview rounds.
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...
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...
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.
Series connectio...
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
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
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...
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
