Electrical Current Circuit Flashcards
What is the purpose of the cell?
To push electrons around the circuit and gives them energy
What is the purpose of the wire?
It conducts the electricity around the circuit
What is the ammeter?
Measures current
What is the voltmeter?
Measures voltage
What is the lamps purpose in an electrical circuit?
It transfers electrical energy into light and heat energy
What is the purpose of the resistor?
To make the current in a circuit smaller
What is the purpose of the variable resistor?
It is adjusted in order to change the current within the circuit
What is the purpose of the motor?
It transfers electrical energy into kinetic energy
What is the purpose of a closed switch?
It allows the current to flow in the circuit
What is the purpose of an open switch?
It stops the current flowing when opened
