Project #493
OBJECTIVE: To make a simple voltage divider.
This circuit is a simple voltage divider with parallel load resistors. The
voltages across both resistors are the same. The current through both
paths are different, due to the resistor values. Since resistor (R3)
(5.1kΩ) is half the value of resistor (R4) (10kΩ), twice the current flows
through R3.
The lights in a house are an example of this type of circuit. All are
connected to the same voltage, but the current is dependent on the
wattage of the bulb.
Fixed-Voltage Divider
Project #494
OBJECTIVE: To make a resistor checker.
Connect the jumper wire to points A & B. Adjust the variable resistor
(RV) to so the meter (M2) deflects to 10. The resistance between points
A & B is zero. Remove the jumper wire and put the 100Ω resistor (R1)
across points A & B. The meter deflects to the 10, indicating a low
resistance. Now replace resistor (R1) with the other resistors. The
meter will display different readings for each resistor.
