Free Running Multivibrator (Astable) with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12139
Indian Lab Suppliers supplies the Free Running Multivibrator (Astable) with power supply (Product ID: 12139) as part of its electronics engineering lab equipment range. It is a training board for studying a transistor free-running (astable) multivibrator, a simple square-wave generator.
Quick Answer
Two NPN transistors and two potentiometers are fitted with an IC-regulated 9 V DC, 50 mA supply. Students study the circuit operation, observe the waveforms at the collectors and bases, and then build an improved free-running multivibrator and compare its output shape. Each half-period is set by an R-C time constant, roughly 0.69RC, so the potentiometers change the frequency and mark-space ratio. Weight and dimensions are not listed; please confirm at quotation.
