What connects the components in a circuit?
An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.
What causes electric current to flow through a circuit?
To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.
How do you control amp output?
Lower the circuit’s amperage by adding a variable resistance device or increasing the resistance on any you already have in the circuit. Variable resistance devices include transistors, FETs and rheostats, which are two-terminal variable resistors. Reduce the voltage in your circuit to lower the amperage.
How does the current move through a circuit?
The electric current moves through each part of the series to get to the next part. Some Christmas lights are wired together in a series cir- cuit. When one bulb goes out, the circuit is broken. With- out the flow of electric current, all of the bulbs go out.
When do we say there is an electric current in a circuit?
If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges. The conventional direction of electric current is taken as opposed to the direction of flow of electrons.
What makes a conducting wire in a circuit?
Conducting wire in an electric circuit is made of metal. If we supply it with a source of energy and a complete circuit, then the electrons will all move in the same general direction through the wire. This movement of electrons through a conductor is electric current.
What causes the current to not flow through a circuit?
If any part is missing or not connected properly, the circuit will not be complete, and electric current will not flow. The electrical energy we use is usually created by a generator, a machine that converts mechani-
