Electricty Flashcards
What is EMF
Electromotive force-ideal voltage of battery
What is TPD
It is the actual voltage as some energy is lost to internal resistance- actual value when battery is connected to a circuit
What is lost volts?
It is the EMF-TPD
How can E=V+Ir be written
E=I(R+r)
E=IR+Ir
What can affect capacitance?
Area of plates
Distance between plates
Material between plates
Capacitance definition
A capacitor of 1 farad will store 1 coulomb of charge when the potential difference across it is 1 volt
What is doping for conductors
It is when silicon is grown on the conductors to include different atoms which are called donors as they give electrons to the conduction band
What is a linear accelerator
It increases the velocity of charged particles by use of electric fields
definition of AC
changes direction and instantaneous value with time
define what is meant by an EMF of 6V
6 joules of energy are being supplied to each coloumb of charge passing through the supply
