Add them up

Answer

There is no 'total' current in a three-phase system. The current flowing in each line (not 'phase') is considered separately. And you most definitely don't 'add them up'!

What is the definition for Input high current and input low current?

Let me first correct the question "current" here should be "tension" current is the speed of the electrons moving through the conductor and tension is the EMF that make the electrons move you cannot input current. the current is the demand of the circuit, depending on the resistance and the EMF(Electro Motoric Force) in other words, the Volts that is applied or input to the circuit.Answer:Any transformer can be used as a up step(inverting) or down step(converting) transformer, for instance 220V - 6V will be a converting and the 220V side will be your primary or high tension input and if you turn it around the 6V side will be your primary or low tension input.


Why input is voltage and output is current in fet?

The input is a Gate that is essentially infinite impedance, so no current. The output is essentially the resistance between Source and Drain, which controls the current flowing through it.

What is the definition for Input low current?

Input Low Current, IIL, is the current that must be sinked (pulled from) an input in order to guarantee that the input is seen as low.

What is current controlled current sources?

A unidirectional current controller device is a type of electrical on/off switch. In order for an item to work that is plugged into a particular outlet, the switch must be in the on position. It is like having lamps plugged into outlets that are controlled by only one switch.
