What do you need to build a circuit?
The things needed to build a circuit are:Circuit elements like resistor capacitors, inductors etcConnectors (cables)A source
A complete electric circuit includes a voltage source current wires and something to ground the flow of current?
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.
Why are amplifiers needed in electronic circuits?
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.
What are three components needed for a circuit to work?
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.
What happens when there is to much current in a circuit?
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.
