10.5 Potential Divider Circuits

Question 1

What does the ratio of the p.d.s across the resisters in a potential divider equal too

Answer 1

The ratio of their resistances

Question 2

What in the formula for V (out) in a potential divider

Answer 2

V(out) = R2 / ( R1+R2 ) = V (in)

Question 3

What is a potentiometer

Answer 3

A variable resistor with a connection on the middle that allows V(out) to be varied from 0V to the maximum source p.d between the middle and an end connection

Question 4

What is a potential divider

Answer 4

An electrical circuit designed to divide the p.d across 2 or more components ( often 2 resistors ) in order to produce a specific output
