Voltage Divider

Question 1

The purpose of a voltage divider is to divide the applied voltage into one or more _____ voltages.

Answer 1

The purpose of a voltage divider is to divide the applied voltage into one or more LOWER voltages.

Question 2

Points along a circuit that provide several LOWER voltages from a single HIGHER voltage source is called what?

Answer 2

Tap off points

Question 3

A series circuit with TAP OFF points is a _______.

Answer 3

A series circuit with TAP OFF points is a voltage divider.

Question 4

What is the difference between Vo and Vout in a voltage divider?

Answer 4

Unloaded output voltage (Vo)
Loaded output voltage (Vout)

Question 5

When a load is added to a unloades voltage divider, voltage ______, resistance ______ and current _______

Answer 5

When a load is added to a unloades voltage divider, voltage decrease, resistance decrease and current increase.

Question 6

An unloaded voltage divider has a (higher or lower) voltage output than a loaded voltage divider?

Answer 6

An unloaded voltage divider has a higher voltage output than a loaded voltage divider.

Question 7

The variation between unloaded Vo and loaded Vout is called _______ or _______.

Answer 7

The variation between unloaded Vo and loaded Vout is called voltage regulation or percent regulation.

Question 8

Percent regulation is found by using what formula?

Answer 8

Percent regulation formula:

% Regulation = 100 × (Vo - Vout)/Vout

Question 9

What is the purpose of a voltage divider?

Answer 9

The purpose of a voltage divider is to supply several lower voltages from one higher voltage source.
