The things needed to build a circuit are:Circuit elements like resistor capacitors, inductors etcConnectors (cables)A source
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
An electrical circuit is used to guide electricity through a path. This is used because when electricity is guided to various things it can power them.Anything that uses electricity.It's called a circuit because the electrons have to circulate back to where they came from.A battery has two poles. The circuit is only complete when both terminals are connected via the device(s) driven.A generator has two poles from the coil inside. Electricity can only flow when both ends of the coil are attached.
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.
If you are talking about the circuits load being to large for the circuits capacity, then the circuits over current or over load protection will come into effect. The fault will open the circuit, thereby isolating the load from the electrical supply source.
For a closed circuit to occur, you need a power source to provide energy, a complete loop or pathway for the current to flow through (including conductive materials and wires), and a load or device that uses the electrical energy flowing in the circuit. This allows the circuit to be continuous and functional.
you need an electrical supply and a load. nice and simple.
To have an electrical current, you need a source of voltage (e.g., battery), a complete circuit (including conductive material), and a load (device that uses the electricity).
A circuit is a complete loop that things can travel around. There are electrical circuits that electrons travel around, and race car circuits around a racetrack, for example.
A complete circuit is made up of a power source (such as a battery), a load (such as a lightbulb), and conductive material (such as wires) connecting the two. When these three elements are connected in a closed loop, electrons can flow through the circuit, allowing the load to receive electrical energy and operate.
The four elements of a complete (electrical) circuit: 1)A source of input (power supply) 2)A means of conductivity (usually wire) 3)A means by which to open and close the circuit (a switch) 4)An output device (motor, light bulb, etc)
battery, wire, and light bulb
Many common household appliances and devices require an electrical circuit to function, such as light bulbs, computers, refrigerators, televisions, and heating systems. Additionally, electronic devices like smartphones, tablets, and gaming consoles also rely on electrical circuits to operate.
voltage and ground
For the circuit to be connected all the way round because if there are breaks in the circuit the electricity will not flow back round. and number 2 a battery or a power source because without power where is the electricity coming from to be honest. Hope it helped. Thanks. xx
A flow of electrons is needed to have a current. And there (usually) must be a complete circuit. And you need a voltage to make the current move around your circuit. All tied up in Ohms Law - which I'll leave to you.
A source of power, a load, and some wire to connect them together.
