Types and Types There are low-frequency and high-frequency models. Screw and spiral coils are classified into a separate category.
Electric current load is a quantity characterizing its properties. Shows how much energy is consumed by electrical appliances. The current power is measured using a special device - a wattmeter. If you connect a meter in series, you can check the current strength. When connecting in parallel, the voltage is determined. The amount of circuit consumption is calculated using the formulas: P = I x U or P = U2/ R = I2 x R. The electrical load is equal to the voltage at the consumer multiplied by the amount of current flowing through it. P = U x I The formula indicates which measurements determine this parameter. If the load is active, it is measured in Watts, the reactive unit of electrical power is VA.
