Description
Available for Pre Order
The AC/DC Smart Power Supply is a Bluetooth Low Energy wireless signal generator. It outputs DC as well as sine, square, positive square, and triangle AC signals. The maximum power output is 10 V at 1 amp and the maximum output frequency is 100 kHz.
The AC/DC Smart Power Supply is controlled through PASCO Capstone or SPARKvue software. The ability to control this power supply through Bluetooth makes it possible for users of Chromebooks, Android, and Apple IOS devices to do experiments with wireless sensors that require a power source.

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.
