Load current is simply the name given to the current drawn by a load from its supply. In the case of a d.c. circuit, this is determined by dividing the supply voltage by the resistance of the load; in the case of an a.c. circuit, it is determined by dividing the supply voltage by the impedance of the load.
If no current flows through a load, then no energy is received by the load. Energy is transferred through the flow of current, so without any current, there is no energy transfer to the load.
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
Throughout the world the system used for home electrification is alternating current (AC).
An ac adapter converts ac current into dc current through a rectifier, and a battery charger outputs dc current at an adjustable powerful charging rate and also converts ac current to dc current to charge different sizes of batteries.
DC current is not used in home wiring. It may be used to power a door bell, alarm system, under counter lights, etc, that uses a transformer powered by AC that converts the power to DC. Other than that homes are wired for AC current only.
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
The terms a.c. and d.c. stand for alternating current and direct current, respectively.
DC Current divided by 1.225
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
Voltage and current will be in phase for a purely resistive load. As a load becomes more inductive or capacitive, the phase angle between voltage and current will increase.
well the difference mainly exists in the method of finding them , these are :-1. in finding DC load line :-open all AC sourcesopen all the capacitors2. for AC load line:-open all the Dc sourcesshort all the capacitors.
If current and voltage of an AC are in phase, then the "power factor" is 100%, and the load is a pure resistance, with no inductive or capacitive reactance (at least at the operating frequency of the AC).
Both AC and DC are current methods in which electrons move along a wire
For any power supply application you hav eto measure the supply specifications with the load specifications. If the supply is AC the load should be designed to use AC and the same for DC to DC. The voltages should match up. The current that the load requires must be less than or equal to the current that can be provided by the supply. Lastly the wires connecting the supply to the load must be sized to carry the current required by the load.
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
The volt ampere (V.A) is the unit of measurement for the apparent power of an a.c. load. It is the product of the supply voltage and the load current.
