What is electricity?
Flow of charge of electrons.
What do electrons do in a circuit?
They carry energy from a source to a component here the energy is released as another type of energy.
Where does the current travel to in a circuit?
From + to -
What is potential difference?
⚡ 2. Potential Difference = How Much Energy Each Lorry (Charge (Q) ) Gets
Where are voltmeters always connected?
Parallel to the components
What is current?
the rate of flow of charge.
What is resistance?
How much a component resists the flow of current.
What happens when electrons move through a conductor?
They collide with atoms in the metal causing the electrical energy turn to thermal.
What is current through a resistor directly proportional to?
to the potential difference. (resistance is constant)
