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
