CIRUITS, V, I, R Flashcards
(12 cards)
What does the source do?
It supplies electrical energy.
What does the function of wires do?
They carry electrons.
What do loads or resistors do?
They use electrical energy.
What is the purpose of a switch in a circuit?
It controls the circuit.
What does a fuse or circuit breaker do?
It acts as a safety device.
What is resistance (R)?
Resistance occurs when electrons move through a load and convert electrical energy into other forms like light or heat.
What is the purpose of loads in a circuit?
To slow down electrons, creating resistance.
How is resistance created with wire diameter?
Smaller diameter wire causes more friction.
How is resistance created with wire length?
Longer or coiled wire gives more path for electrons.
How is resistance affected by conductor metals?
Poor conductor metals create more resistance.
How can electrons move?
A complete circuit is needed
Electrons move how?
Through a circuit
