a light sensor is based on a photodiode that requires a minimum photon energy of 1.30 ev to create mobile electrons. 200nM
A sensor is a device that recognises and reacts to a certain kind of input from the outside world. The input can be any number of environmental events, including light, heat, motion, moisture, and pressure. The output is typically a signal that is processed into a human-readable form at the sensor location or electronically sent over a network to be read or used in other operations. In the internet of things, sensors are crucial (IoT). They enable the development of an ecosystem for gathering and processing information about a particular environment, allowing for easier and more effective monitoring, management, and control.

The formula to use is: I = (<span> ΔV / R )
Once you solve for R, your new formula would be: R= (</span><span> ΔV / I )
Plug in your values to get: R = (1.5V / .75A )
Finally, R = 2</span><span>Ω</span>
The particles that carry charge through wires in a circuit are mobile electrons. The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field.
