Series and parallel electrical circuits Flashcards
Which component provides power to the circuit?
A cell, battery (combination of cells) or power supply provides power to the circuit.
Which component measures the current or flow of charge through the circuit?
An ammeter measures the current (flow of charge) through the circuit. Current is measured in units called amps.
What are cells
Cells provide the energy for many electrical devices to function - like torches, mobile phones and laptops. Cells come in different sizes and shapes.
What is potential difference
Potential difference is the amount of energy transferred by each unit of charge passing between two points of a circuit.
How are components, like motors, lamps and cells, represented in a circuit diagram?
Circuit symbols represent each component
