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
