Current 1 Flashcards
What is an electric circuit?
An electric circuit is a loop of wire that is connected end to end with an energy source, such as a cell or a battery
What allows the transfers of energy from the battery to the wires in a complete circuit?
Complete circuits allow the transfers of energy of energy from the battery to the wires by an electric current
What happens if there are gaps in a circuit or electrical insulators?
Current will not flow if there are any gaps in the circuit or if there are any components that are electrical insulators
Explain the difference between a cell and a battery?
A battery is 2 or more cells
What is current in an electric circuit?
Current is the amount of charge flowing per second in a complete circuit
What symbol is used to represent current?
Current is given the symbol I and is measured by an ammeter in amperes (A), named after the french scientist
How does a battery affect the movement of electrons in a circuit?
When a battery is connected, the electrons in all parts of the wires within the circuit move in the same direction, at the same time, and at the same rate. This movement is current
