Electricity: The Basics of a Circuit- Pg. 12

Requirements for an Electrical Current1. There must be a closed conducting path which extends from the positive terminal to the negative terminal.

3. All materials need to be connected together forming a complete circuit.

2. All connections must be made by materials that are capable of carrying a charge.

At the end of the lesson I should be able to:

define an electrical circuit and the variables associated with a circuit.Statement of Inquiry:

Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk.

If the three requirements of an electrical circuit are met, then

charge will flow through the external circuit. It is said that there

is a current - a flow of charge.

INQUIRY QUESTION:

a. There must be a closed conducting path which extends from the positive terminal to

the negative terminal.

b. All connections must be made by materials that are capable of carrying a charge.

c. All materials need to be connected together forming a complete circuit.

Debatable Question:




Using the word current in this context is to simply use it to say that something is

happening in the wires - charge is moving. Yet current is a physical quantity which

can be measured and expressed numerically. As a physical quantity, current is the

rate at which charge flows past a point on a circuit. As depicted in the diagram below,

the current in a circuit can be determined if the quantity of charge Q passing through

a cross section of a wire in a time t can be measured. The current is simply the ratio

of the quantity of charge and time.

The standard metric unit for current is the ampere. Ampere is often shortened to Amp and is abbreviated by the unit symbol A. A current of 1 ampere means that there is 1 coulomb of charge passing through a cross section of a wire every 1 second.

1 ampere(A) = 1 coulomb(C) / 1 second (s)

ELECTRIC CURRENT READING

• A current-carrying wire has a net electric charge of zero

• Electric current is the flow of electric charge

• In solid conductors, the electrons carry the charge through the circuit because the are free to move through the atomic network. These electrons are called conduction electrons.

• In fluids, such as the electrolyte in a car battery, positive and negative ions as well as electrons may compose the flow of electric charge.

• Electric current is measured in amperes, for which the SI unit is symbol A. An ampere is the flow of 1 coulomb of charge per second.
