What is current?
The rate of flow of charge
What type of circuit is shown in the image?
Series circuit
What equation links potential difference, current and voltage?
Potential difference = current x resistance
V = I R
For a given potential difference, what happens to the current when the resistance increases?
The current decreases.
What is the rule for current in a series circuit?
Current is the same everywhere in the circuit
