Components In A Circuit And There Purpose Flashcards
To Be Able To Explain The Purpose Of Different Components In A Circuit (8 cards)
What is the purpose of a Voltmeter in a Circuit?
A Voltmeter measures the Potential Difference between two points in a Circuit.
What is the purpose of an Ammeter in a Circuit?
An Ammeter measures the current flowing through the Circuit at that point.
What is the purpose of a Lamp in a Circuit?
A Lamp transfers energy out of the Circuit via Radiation Transfer (Light).
What is the purpose of a Resistor in a Circuit?
A Resistor transfers energy out of the Circuit, usually to Thermal Energy, heating
the Resistor up.
What is the purpose of a Cell in a Circuit?
A Cell stores energy, provides the potential for the Circuit.
What is the purpose of a Battery in a Circuit?
A Battery is more than one Cell, connected in Series, adding up the Potential Difference of each Cell.
What is the purpose of a Switch in a Circuit?
A Switch closes and opens a small break in the circuit. This allows the
Current to flow or stop it.
What is the purpose of a Variable Resistor in a Circuit?
A Variable Resistor is like a regular Resistor, except the Resistance can be changed.
