4b.3 Potentail dividers

Question 1

what is a potential divider circuit

Answer 1

it is a circuit designed to provide a specific voltage supply by splitting the emf across two resist

Question 2

what is an equation we can set up using a potential divider

Answer 2

V1/R1=V2/R2 ——> V1/V2=R1/R2

Question 3

how is potential dividers used

Answer 3

we set up two Variable resistors in order to have a certain Pd given across two of them, a Pd that we need, then we would attach a component parallel to the resistor so it can experience the same resistance

Question 4

what is the potential divider equation

Answer 4

Vout = Vin x R2/(R1+R2)

Question 5

what is the potentiometer

Answer 5

it is a version of a potentail divider where a resistater wire is used in two parts gving us two resistors. there is a sliding connection (wiper) can can be adjusted in order to alter the two resistances, therfore changing the output Pd from the potentiometer
