Q1. How many current in 3 phase
Ans. 
The current in a 3 phase system depends on the voltage and power of the system.
• The current in a 3 phase system can be calculated using the formula: I = P / (sqrt(3) * V)

• Where I is the current, P is the power, and V is the voltage

• For example, if the power is 1000W and the voltage is 240V, the current would be approximately 4.33A

Q3. How check AC DC current
Ans. 
To check AC DC current, use a multimeter set to the appropriate setting and connect the probes to the circuit being tested.
• Set the multimeter to the AC or DC current setting depending on what you are testing.

• Ensure the multimeter probes are connected correctly to the circuit being tested.

• Read the current measurement displayed on the multimeter.

• For AC current, make sure the multimeter is set to the appropriate range (e....read more

Q4. How Check of cable continuity
Ans. 
To check cable continuity, use a multimeter to measure resistance between two points on the cable.
• Use a multimeter set to the resistance or continuity mode.

• Connect one probe to one end of the cable and the other probe to the other end.

• A low resistance reading indicates good continuity, while a high resistance or infinite reading indicates a break in the cable.

• Check for continuity in each conductor of the cable separate...read more

Q6. Name of the motor work in AC and DC
Ans. 
The motor work in AC is based on electromagnetic induction, while in DC it is based on the Lorentz force principle.
• AC motors work on the principle of electromagnetic induction, where a changing magnetic field induces a current in the rotor coils.

• DC motors operate based on the Lorentz force principle, where a current-carrying conductor in a magnetic field experiences a force.

• Examples of AC motors include induction motor...read more
