Gain in Current = Voltage / Resistance For example, if the voltage across a resistor is increased from 12 volts to 24 volts, and the resistance remains constant at 12 ohms, then the gain in current will be: Gain in Current = 24 volts / 12 ohms = 2 = doubled (from 12 amps to 24...

In apurely resistive AC circuit, power is simply power. If we add inductance or capacitance to the circuit, the situation becomes very different. As you now know, capacitance and inductance affect the phase relationship between voltage and current, and we need to understand s...
The reactive power-voltage control link mainly realizes reactive power-voltage sag control, and the output voltage amplitude command Eref is obtained according to the current output reactive power and the given sag relationship. $$ E_{{{\text{ref}}} = E_{{\text{n}}} + K_{{\text{q}}...
