electron flow and conventional current Flashcards
1
Q
What is electron flow
A
Electron flow is the actual movement of electrons in a circuit — from the negative terminal to the positive terminal.
2
Q
What is conventional current?
A
Conventional current is the imaginary flow of positive charge — from the positive terminal to the negative terminal of a power source.
3
Q
Why is conventional current used even though electrons flow the opposite way
A
Before electrons were discovered, scientists assumed current flowed from positive to negative, and this convention is still used in circuit diagrams today.
4
Q
What is the unit of electric current
A
The unit of electric current is the ampere (A).
5
Q
What does 1 ampere represent
A
1 ampere = 1 coulomb of charge flowing per second
