## 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-
