Q

name and explain the two types of circuits

A

series - a circuit which provides only one pathway for the flow of current

parallel - a circuit which provides more than one pathway for the flow of current

SERIES CIRCUIT

what happens to voltage na current

A

current (I) stays the same at any point

voltage (V) divides in a series circuit

Q

SERIES CIRCUIT

what happens when u add resistors in a series circuit

A

RT (total resistance) increases

therefore current (I) will DECREASE because

IT = VT/RT
(I)current is inversely proportional to resistance (R)

Q

PARALLEL CIRCUITS

what happens when u add resistors in a parallel circuit

A

RT (total resistance) DECREASEs

therefore current (I) will INCREASE because

(I)current is directly* proportional to resistance (R)
