Three things that are needed to have an operating electrical circuit are:
1. Electric potential difference or voltage.
2. Conductive path, which allows the movement of charges such as wire.
3. Resistor, which acts as an electrical resistance and loosely defines any object that uses electricity to do work.

∙ 13y agoEvery circuit in existence will need to be composed of at least a current/voltage source and a conductor (for example, wiring). For example, most electric heaters are this simple (most include a switch to turn it on or off, but the basic idea stands).
For the circuit to do something useful, a third element must be added - what is generally considered under the term "load". The "load" is the - well - load, placed on the source of energy provided, and is the part that "does something". In the above example, the heating wires in a heating unit also serve as the load, as these wires have increased resistance (this would be considered a purely resistive load). Other types of load also exist (inductive load is an example - like an electric motor).
But in essence, the basic components of a circuit are: the energy source (voltage/current), a conductor to the load and back, and a load.

A battery(or an electricity source), conducting wire from which electricity can flow, and a resistror(which is anything like lamp, bulb,ceiling fan etc.) !!

Part of a circuit that does work?
Three basic parts of a circuit are: 1. Active components = source of energy 2. Transmission Lines = wiring and control devices 3. Passive components = load or user of energy
How can an ohmmeter be damaged?
By connecting it to a circuit with the power still applied. Ohm meters work best when the component under test is removed from the circuit to eliminate parallel paths of current through other components.
What are all the parts on a circuit board?
to assemble a circuit you just need to connect one end of a wire to the battery and the other to the light bulb ( could be another electrical device) now take an other wire and connect on end of it to the other side of the battery and the other to the other side of the light bulb( or an other electrical device. if your circuit is including a switch this is how you do it: ( you will need three wires for this circuit if you have one electrical device) connect one end of the wire to the battery and the other to the switch.Grab another wire and attach one end of it on the other side of the switch and the other to the electrical device (light bulb). Grab another wire and attach one end of it to the other side of battery and the other to the other side of your electrical device. And there you have it how to assemble a circuit
How does High and Low voltage cut out circuit works if voltage varies?
I assume you mean - 'Why does a circuit fail to work if the operating voltage is too high or too low?' A certain specific voltage is needed to overcome the natural resistance in circuit components. For instance in simple transistors, this is 0.7V to get the transistor to switch on and 1.4V is lost across the switched junction. This is why may circuits operate at above 3V. The rest of the circuit is designed to operate at the specified voltage and if you go too high, too much current will flow through the circuit and it will fail in the same way a fuse will blow if too much current is passed through it.
What is status of a circuit that is complete and unbroken with flowing electric current?
A circuit that is complete and unbroken with flowing electric current normally has steady supply of voltage with no broken links. Electrical energy flows to light up a bulb or do similar work. Its status is complete, nothing else is needed.
Why does a circuit work?
It works with a connected wire and all the components inside a circuit.

Is a switch needed to make a circuit work?
Not always. Depends on the circuit.
How does a torch work-circuit?
A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

What are the components of a work measurement system?
A work measurement system has three components: preferred methods, time values, and reporting.
How will an electrical circuit behave if there is an open circuit?
The circuit is incomplete, you will have no continuity, no flow of current to the load or other components. The voltage across every component in the circuit is zero. No part of the circuit stores or dissipates any energy. In short, the circuit doesn't work.
How do modern defibrillators work?
For example, a ‘shock’ circuit used in a defibrillator has three key components: a high voltage source, a capacitor and switches. The charges pulse the heart, pumping blood.
What does a printed circuit board do?
A Printed Circuit Board (PCB) is the skeleton of most electronic devices. It provides not only a solid physical base for the components to be mounted upon, but also the electrical interconnects (traces) between the components.
Why do technicians label their circuit component values?
For exactly the same reason that the components are manufactured with differentvalues. The reason is that a circuit will work the way you want it to work only if youbuild it with components of certain definite values, and if you use other values thenthe circuit will not work.When you write or draw a description of the circuit, it's not good enough to say"hook up a capacitor here" and "put a resistor there". If their values are wrong,then the circuit either produces nothing or else it produces smoke.
Why does short circuit break whole circuit?
Because a whole circuit needs a short circuit to work. It's like a remote; the remote is the whole circuit and the batteries needed are the short circuit. if those batteries are broken, the remote won't work. In other words, without a short circuit, a whole circuit can not occur successfully. Hope this helped, Charlie the Grey
How does the fuse work in a plug?
The fuse in a plug is designed to blow and cut off the current in a circuit before the rest of the wiring and components are damaged or burnt-out should a short-circuit occur.
