How to find resistance, inductance, and capacitance of a load/device
I'm planning to make a proper simulation of a circuit. Before the simulation, I need information about the load (resistance, inductance, and capacitance).
Example: the load is a CPU. range of wattage ...

How does capacitive loading and inductive loading differ from resistive load?
A voltage source is loaded when current is drawn from it. Usually we have voltage sources in circuits and not current sources. A resistive load draws current from a voltage source that is a function ...

Watt meter and load
I have recently purchased a watt meter from Adafruit to measure the cumulative watthours of a non-constant (DC) current.
When I use a multimeter to test the voltage and amperage, I get what I expect: ...

Is "load sharing" when 2 power supplies are connected in parallel or when a battery is connected indirectly to the load?
I see the term "load sharing" used in two completely different cases:
When 2 power supplies are connected in parallel, a technology that ensures that each delivers half of the load current: ...
