Electricity Flashcards
1
Q
Increasing pd
A
Increasing pd in a circuit accelerates electrons faster, increasing drift velocity and current.
This means electrons have more energy that is transferred to atoms when moving electrons collide with them, transferring energy to them as vibrational energy. This increases temperature and therefore makes collisions more frequent, increasing resistance.

3
Q
Resistance & Current
A
As resistance decreases, current increases
