This page contains our IB Physics definitions for sub-topic D2. By learning each one of these definitions, you will fully cover the content for IB Physics 'Further electromagnetic fields'.
HL
Electric potential difference
It is the work done moving a test point charge per unit test point charge
HL
Electric potential energy
It is the work done in moving a charge from any point in space to infinity
HL
Electric potential gradient
It is the average electric field strength over a specified distance
HL
Equipotential
It is the line of zero potential difference where no work is done moving an object
HL
Potential
It is the energy per unit test point due to the field
Potential difference
It is the energy difference or work done per unit charge moved between two points
