1
New cards

electric current

is the flow of electrons/ charge around a circuit

flows around from cell to back comp circuit

if gap incomp no current flow

2
New cards

resistance

hindrance to the flow of current

collision between charge carriers and fixed positive ions in the material

3
New cards

resistance unit

Ohm

4
New cards

ohms law rule

voltage across a component is proportional to the current through

5
New cards

filament lamp

as current inc, the lamp is hotter

resistant inc, gradient dec

ohm law not followed

6
New cards

diode

infinite resistance in one side none in the other

ohm law not followed
