How do you calculate current for a three phase heater?

Current intensity: I=U/R=380/18=21.1 amps. Total power: P=3*U^2/R=3*380*380/18=24,066.7 watts. \r\nScientifically, the amount of electricity that passes through any cross-section of a conductor in a unit of time is called the current strength, or current for short. It is usually denoted by the letter I, and its unit is the ampere (André-Marie Ampere), 1775-1836, French physicist and chemist, who was an accomplished researcher in electromagnetic action and also contributed to mathematics and physics. The international unit of current, the ampere, is named after her. The abbreviation "ampere" and the symbol "A" also refer to the directional movement of electric charge in a conductor. \r\nMore about how to calculate the current of a three-phase heat pipe, go to: /ask/ac032d1615835052.html?zd to see more content
