Seven LED’s of different wavelengths mounted on a moulded plastic case (142x80x40) mm approx, selectable through a rotary switch. The apparatus uses a 5V DC input external 4mm sockets. To monitor the current and voltage across each LED additional 4mm sockets are provided to connect voltmeter and ammeter. The operating voltage for the LED’s can be adjusted with the help of potentiometer.

A simple portable device for determination of planck’s constant. On providing input of 5V DC, the voltage across the three LEDs, can be varied through a knob and can be measured across a pair of 4mm sockets. The voltage at which a particular LED glows helps in computing the planck’s constant. Complete assembly mounted in plastic case, with circuit printed on it. Provision for external LEDs with fixed as well as variable voltage. Complete with user instruction manual.
