Study of Phase measurement by super position with power supply and 1 multi range meter (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12271
Indian Lab Suppliers supplies the Study of Phase measurement by super position with power supply and 1 multi range meter (C.R.) (Product ID: 12271) as part of its electronics engineering lab equipment range. It teaches phase relationships in RC, LR and LCR circuits by adding measured voltages as phasors.
Quick Answer
A mains transformer gives 10, 20, 30, 40, 50 and 100 V AC tappings (100 mA), and a digital panel meter with 20 V and 200 V ranges reads each voltage. Students measure the voltages across resistor, capacitor and inductor in series circuits and draw the phasor diagram by superposition, which gives the phase difference between VR and VC in an RC circuit, the phase angle in an LR circuit, and the relationships among VR, VL and VC in an LCR circuit. Four inductors are fitted. The 100 V tapping can give a shock, so connect circuits with the supply switched off.
