About This Product
Teachers use the box to explain voltage, current, resistance and power at low laboratory levels. Students wire it in with the supply off, choose the resistance value, switch on the low-voltage supply and record current and voltage readings, then compare the measured values with their calculations. Besides buyers across India, the Electrical Resistance Box 500 Ohms can be exported to institutions in Bahamas, Mauritius, New Zealand, Kuwait and Jamaica.
