High speed and high resolution. Breakthrough ADC technology switches from 8 to 16 bits in the same oscilloscope.
DrDAQ is used here as a light sensor with a temperature and voltage sensor to measure the light and temperature output of a 12 W bulb over a set voltage range so that the efficiency of the light bulb can be calculated.
Currently manufacturers are producing more efficient light bulbs, but what does this mean? Are they producing more light and less heat or are they using less electricity? This experiment provides data to calculate the efficiency of a bulb, the power output and allows you to calculate heat loss from a bulb
This experiment requires some knowledge of energy efficiency and transfer.
Create your table as shown below:
|Voltage on sensor in volts
|Temperature in deg C
Allow the readings to reach a constant level before increasing the voltage.
What are the relationships between light and voltage, light and temperature, voltage and temperature?
