Electric field Flashcards
1
Q
What is the equation of the Coulomb’s law?
A
2
Q
What is the formula of electric field strength
A
Force / Charge (NC^-1) or Voltage / distance (Vm^-1)
3
Q
What is the electric potential?
A
The amount of work done to move a unit charge from infinity to a specific point against an electric field
4
Q
What Capacitance (C)
A
Charge / Voltage (QV^-1)
5
Q
How does a capacitor work?
A
It discharges through a resistance, the negative charge on one plate flows through R and is neutralized by the positive charge on another plate
