Q1. What is current 3 phase voltage
Ans. 
Current is the flow of electric charge. 3 phase voltage refers to the voltage in a three-phase power supply system.
• Current is measured in amperes (A)

• 3 phase voltage is typically 208V, 240V, 480V, or 600V

• In a three-phase system, there are three voltage sources that are 120 degrees out of phase with each other

• The voltage between any two phases is called line voltage, while the voltage between any phase and neutral is cal

Q2. 3 phase voltage= 440
Ans. 
440V is the standard voltage for 3-phase power supply.
• 440V is the root mean square (RMS) voltage of the three alternating currents in a 3-phase power supply.

• It is commonly used in industrial and commercial applications.

• The voltage may vary depending on the country's electrical standards and regulations.

Q1. What is ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit...read more
