Activities
01) Ohm's Law Using AC/DC Smart Power Supply
The purpose of this experiment is to verify Ohm’s Law for commercially manufactured resistors and to examine the limits of validity for Ohm’s Law. The behavior of resistors, a diode, and a light bulb are examined.
02) Series and Parallel Circuits Using AC/DC Smart Power Supply
Series/Parallel circuits are reduced to an equivalent resistance and that resistance is verified by measuring the total current and total voltage. In a second stand-alone experiment, the behavior of lamps in series, parallel, and series/parallel is qualitatively examined.
03) Kirchhoff’s Circuit Laws Using AC/DC Smart Power Supply
Kirchhoff’s Junction Rule and Loop Rule form the basis of all circuit analysis. Here we verify the laws for a resistive circuit.
04) RC Circuit Using AC/DC Smart Power Supply
The manner by which the voltage on a capacitor decreases is studied. The half-life for the decay is measured directly and also calculated using the capacitive time constant.
05) General Properties of Diodes Using AC/DC Smart Power Supply
The purpose of this experiment is to investigate the characteristic curves (I vs. V) of various types of diodes and to determine their “turn-on” voltages.
