All Flashcards
What happens if a circuit loop is open?
Electricity will not flow, and devices on the circuit will not work.
What happens when electrons travel through a device in a circuit?
They transfer their energy to the device, causing a voltage drop.
What is the effect of adding resistance to a circuit?
It reduces the current to the desired value, often converting energy to heat.
What are the differences between series and parallel circuits?
Series: One path for current | Parallel: Multiple paths for current.
What is a circuit?
A closed loop of electrical current.
Define electrical current (I).
The flow of electric charge through a conductor.
What is voltage?
The amount of energy each charge carrier is given in a circuit.
Define resistance.
The opposition to electrical current.
What is electric power?
The rate at which electrical energy is used in a circuit.
