- Q1. What is transformer
- Ans.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers consist of two coils of wire, known as the primary and secondary coils.
The primary coil is connected to a power source, creating a magnetic field when current flows through it.
This magnetic field induces a voltage in the secondary coil, transferring energy from the primary t...
- Q2. How to calculate three phase current
- Ans.
Three phase current can be calculated using the formula: I = P / (√3 * V * cos(θ))
Calculate the power (P) in watts
Determine the voltage (V) in volts
Find the power factor (cos(θ))
Use the formula I = P / (√3 * V * cos(θ)) to calculate the three phase current
- Q3. Power Factor meaning
- Ans.
Power Factor is a measure of how effectively electrical power is being used in a system.
Power Factor is the ratio of real power to apparent power in an electrical system.
It is a number between 0 and 1, with 1 representing perfect efficiency.
Low power factor can result in increased energy costs and inefficient use of power.
Power Factor can be improved by using power factor correction devices like capacitors.
Example: A s...

- Q1. M15 grade ratio
- Ans.
M15 grade ratio is the mix ratio of concrete used in construction projects.
M15 grade concrete has a mix ratio of 1:2:4 (1 part cement, 2 parts sand, 4 parts aggregate)
It is commonly used for non-structural works like flooring, pathways, etc.
The strength of M15 grade concrete is 15 MPa after 28 days of curing

- Q1. Minimum grade of concrete
- Ans.
Minimum grade of concrete is M10, which is used for plain cement concrete works.
Minimum grade of concrete is M10 as per IS 456:2000.
M10 grade concrete has a compressive strength of 10 N/mm^2 after 28 days of curing.
It is commonly used for plain cement concrete works like levelling course, bedding for footing, etc.
