What is emf

the amount of chemical energy converted to electrical energy per Coulumb of charge passing through a power supply

2
New cards

What is terminal potential difference?

the potential difference across the terminals of a cell.

3
New cards

why is terminal pd always less than emf

becasue the cell has internal resistance

4
New cards

what are lost volts?

the voltage lost inside the cell due to internal resistance,

lost volts = Ir

5
New cards

what is the equation for terminal pd?

V= ε- Ir
