Peak & Average voltage Determination in an A.C. Circuit with power supply and 2 meters Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12214
Indian Lab Suppliers supplies the Peak & Average voltage Determination in an A.C. Circuit with power supply and 2 meters (Product ID: 12214) as part of its electronics engineering lab equipment range. It is a self-contained board for finding the peak value of an AC voltage and the average value of its half-wave rectified form.
Quick Answer
In the first experiment, the peak voltage of the AC is found and used to calculate the average of the half-wave rectified wave, which is the peak divided by π. In the second, the peak value is found by a null-deflection method against the built-in 12 V DC, 10 mA IC-regulated reference. A mains step-down transformer gives 3, 4.5, 6 and 9 V AC tappings at 10 mA. Readings come from an AC/DC voltmeter and a DC voltmeter, both 0–15 V on 65 mm dials; two SPST switches, a potentiometer and a diode complete the circuit.

Frequently Asked Questions
How is the average voltage found?
From the measured peak: average of half-wave rectified AC = peak / π.
What is the null-deflection method?
The unknown peak is balanced against the adjustable DC reference until the meter reads zero.
Is an oscilloscope needed?
No, the board needs no other apparatus.
