An electrical circuit needs Voltage-electrical pressure pushing electrons, and Amprege-electron flow through a conductor. P=IxE (Power= Voltage x Amprege.
Electrical devices need an electrical circuit.
the main diffrent between electrical and electronics is Electrical is study of electriccity and electronics is study of the electical or databus controlle circuit. All machine need electrical Power. how much power it need? which electrical contolled it need? that study in Electrical but in Electronics how much power we need? and how to create that power for that we use some electronics circuit. that sutdy i electonics. It is a simple diffrent between electrical and elecronics. ANSWER: The difference is the study of electrons behavior. Electrical main concern is electrons flow. Electronics is a study of electrons emission.
Some electrical machines work on the principle of electromagnetic induction. For such events to occur, we need inductor due to which reactive power flows in the circuit. Since, this power is due to the energy storing elements in the circuit like inductor and capacitor. That is why, we need reactive power in a electric circuit.
1)to reduce the power loss. 2)to avoid the noise.
A circuit needs at least three electrical contacs.
Analysing a circuit with a shorted component need specialised electrical test equipment.
to turn electrical potential into mechanical work/motion.
You need to take it to service center
You would need to shutdown the power whenever you are working on the electrical service.
When you turn It off it breaks the circuit. When it is turned on it closes the circuit. To have a light bulb turn on it need to have continuity. Hope that helps
Assuming you are talking about electrical circuits: "Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.
The first part is that you need a power source. The second thing is that you need a load. The third thing is that you need the power cables.
