- 1Electric fieldThe region in which a charge particle experiences a force of attraction or repulsion.
- 2Electric field strength E=F/q or F=EqA charged particle experiences force inside an electrical field
E= Electrical force/strength (NC-1)
F= Force exerted on charge in field (N)
q= Charge (c) - 3Gravitation potential energy is gained when mass elevates (work is done) W=EP=Fd and EP=Eqdq= charge of particle (c)
Ep= electric potential (or work) (J)
E= electric field strength (NC-1)
W= work done
F= Force exerted on charge in field (N) - 4Potential difference V= Ep/qChange in potential energy per coulomb of charge between 2 points (voltage)
V= voltage (V)
Ep= change in potential energy (J)
q= charge (c) - 5Kinetic energy Ek= 1/2mV²Principal = conservation of energy
Electric fields used to accelerate charge particles where Ep changes into Ek - 6Electric fields between parallel plates E= V/d direction - towards negative platefield strength + direction between plates same at any point (uniform field)
E= electric field strength (Vm-1)
V= voltage (V)
d= Distances between plates (m) - 7Current I= q/tMeasure of amount of charge to pass a point per second.
I= current (amps A)
q= charge (c)
t= time
1 amp = 1 coulomb of charge per second
