What is potential difference?
The energy per unit charge transferred to a component
2
New cards
What is the unit for potential difference?
Volts
3
New cards
Where does the voltmeter have to be in the term of the component
the voltmeter should be connect in parallel with the component
4
New cards
why do voltmeters have to be connected in parallel?
because it measures the potential difference in electron energy across the component. Each compont uses energy
5
New cards
What is potential difference directly proportional too?
current
6
New cards
What is resistance opposite too?
the rate of the flow of charge
7
New cards
What is the equation for potential difference?
Potential difference= energy transfer/ charge
