What is the load current if the power factor is 1.0 or100 percent?

The load current in an electrical system isn't determined solely by the power factor. The power factor, which can range from -1 to +1, is a measure of how effectively the electrical power is being converted into useful work output. A power factor of 1 (or 100%) signifies that the power is being used entirely effectively, with no reactive power.

However, to determine the load current, you would also need to know the power (in watts) and the voltage (in volts) being used in the system. The formula to calculate current (I) is: I = Power (P) / Voltage (V). So, if you have a power factor of 1, it means that all the power is being used effectively, but it doesn't directly determine the load current.
