Planck’s Constant
Planck’s Constant:MPH-EE-32
- Seven LED’s of different wavelength mounted on a plastic moulded case. Selectable through a rotary switch surrounded by LED’s. The apparatus uses a 5V DC external voltage via.
- 4mm colour coded sockets indicated with 5V and 0V respectively.
- To monitor the current and voltage across each LED 4mm sockets are provided to connect voltmeter and current meter indicated with ‘V’ and ‘A’ respectively.
- The operating voltage for the LED’s can be adjusted with the help of potentiometer fitted on the base.
- A viewing tube with an eyepiece is also provided with the instrument for ease in viewing the starting voltage for the LED’s.
