electricity Flashcards
1
Q
define electric current
A
current is how fast the charge is flowing
2
Q
Give the equation that links time, charge and electric current
A
charge = current x time
3
Q
define potential difference
A
voltage is the energy given to each charge
4
Q
Give the equation that links energy, potential difference and charge
A
energy = voltage x charge
5
Q
Explain how components in a circuit causes resistance
A
resistance is caused by collisions between the ions and the electrons in the wire
6
Q
Give the equation that relates potential difference, resistance and current
A
voltage = current x resistance
