Electron = -1.602x10-19
Neutron = NIL
Proton = +1.602x10+19
IONS = Positive and Negative
Current-(I) Controlled the movement of electron through a substance is called Current.
Direction of the flowing current is opposite direction of the flowing electron.
Direction of the flowing current is opposite direction of the flowing electron.
Electromotive Force-(EMF) EMF is the force that causes a current (I) of electricity to flow.
Total voltage in a electric circuit generate by the sources or battery.
It is applicable for electric field.
Total voltage in a electric circuit generate by the sources or battery.
It is applicable for electric field.
Potential Difference-(V) Work done per unit charge to more charge between the -ve and +ve terminal of the battery.
Potential Difference between 2 points in a circuit is electrical pressure or voltage required to drive the current between them.
Potential Difference between 2 points in a circuit is electrical pressure or voltage required to drive the current between them.
It is applicable for magnetic, gravitational and electric field.
Resistance-(R) Opposition of flow of electron as well as the opposition of flow of current.
ρ = nature of material
l = length
A = cross section area
R = Resistance
Conductance-(G)
Conductivity-(σ)
Resistance-(R) Opposition of flow of electron as well as the opposition of flow of current.
l = length
A = cross section area
R = Resistance
OHM's Low- For a fixed metal conductor, the temperature and other condition remaining constant the current (I) through it is proportional to the potential difference (V) between its end.
Relation between power, voltage and current-
P = Power
V = Voltage
I = current
