Q1. What is the si unit of resistance ?
Ans. 
The SI unit of resistance is ohm (Ω).
• The SI unit of resistance is named after the German physicist Georg Simon Ohm.

• Resistance is the measure of opposition to the flow of electric current.

• Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance.

• The symbol for ohm is the Greek letter omega (Ω).

Q3. What are the Electrical fault occurs in the motor
Ans. 
Electrical faults in motors can include short circuits, open circuits, insulation breakdown, and overloading.
• Short circuits occur when there is a direct connection between the motor windings, causing excessive current flow.

• Open circuits happen when there is a break in the electrical path, preventing current from flowing.

• Insulation breakdown occurs when the insulation material surrounding the motor windings deteriorates...read more
