Answers
A thermistor’s “b” value, or beta value, is an indication of the shape of the curve representing the relationship between resistance and temperature of an NTC thermistor. Calculating the beta value is a vital step in the component selection process as it gives the characteristic at a given temperature vs the resistance for a specific application.
Beta Value and NTC Thermistors
NTC thermistors are non-linear resistors that alter their resistance characteristics with temperature. Simply put, as temperature increases the thermistor’s resistance decreases. The manner in which the resistance of a thermistor decreases is related to a constant known in the thermistor industry as beta (β).
Beta is measured in degrees Kelvin (K) and is computed based on the formulation given below.

Answer:
photoreceptor are cells
Explanation:
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential.
