chapter 15

conventional current

flow of positive charge from positive terminal of battery around the circuit to the negative terminal

electrical current

The rate of flow of charge per second

Potentional difference

the amount of work done per unit of positive charge

variable resistors

resistors with adjustable resistance

ohms law

the current through a resistor at constant temperature is directly proportional to the potential difference across the resistor

electrical resistance

resistance of conductor to the flow of current

resistance

how much a component is able to slow down the flow of electrons through component

2 factors that affect resistance of conductors

material conductor made of, length of conductor

parallel circuit is a

current divider
