Q3. What is mutual Induction
Ans. 
Mutual induction is the process where a changing current in one coil induces a voltage in another coil.
• Mutual induction occurs when two coils are placed close to each other and the magnetic field produced by one coil induces a voltage in the other coil.

• The induced voltage in the second coil is directly proportional to the rate of change of current in the first coil.

• This phenomenon is the basis for the operation of tran...read more

Q4. Calculate weight of 1mX1mx3mm MS plate?
Ans. 
The weight of a 1mX1mX3mm MS plate can be calculated using the formula: Weight = Length(m) x Width(m) x Thickness(mm) x Density of MS (kg/m^3)
• Convert the thickness from mm to m (3mm = 0.003m)

• Density of MS is typically around 7850 kg/m^3

• Calculate the weight using the formula: Weight = 1m x 1m x 0.003m x 7850 kg/m^3
