P2 - Current and Circuit Symbols (1) Flashcards
1
Q
What is Current?
A
Current is the flow of electrical charge.
2
Q
What is the Unit of Current?
A
The unit of current is the Ampere (A).
3
Q
What is Potential Difference/Voltage?
A
PD or Voltage is the driving force that pushes the charge around.
4
Q
What is the Unit of PD/Voltage?
A
The unit of PD/Voltage is the Volt (V).
5
Q
What is Resistance?
A
Resistance is anything that slows the flow down.
6
Q
What is the Unit of Resistance?
A
The Unit of Resistance is the Ohm (Ω)
7
Q
What is the equation linking Current, Charge flow and TIme?
A
The equation is Q=IT
Q=Charge(Coulomb) I=Current T=Time(seconds)
