Why is the water clearer in the winter? It’s simple really…more light + warmer water = a greater concentration of organic (living AND decaying) material in the water column. Less light + colder temps = less organics and better vis. At what temp should you drip faucets? 28 degrees Which pipe will freeze first? Generally […]
What are the two types of spread spectrum techniques?
What are the two types of spread spectrum techniques? Types of Spread Spectrum. Spread Spectrum can be categorized into two types: Frequency Hopping Spread Spectrum (FHSS) Direct Sequence Spread Spectrum(DSSS) Which filter is used to get the final FHSS signal? Band pass filter Is CDMA and DSSS same? Direct sequence spread spectrum, DSSS is a […]
Does higher current mean more resistance?
Does higher current mean more resistance? This is resistance. The circuit with the higher resistance will allow less charge to flow, meaning the circuit with higher resistance has less current flowing through it. What happens in brightness of bulb if the length of Resistance of wire is increased? As resistance of the rheostat increases, the […]

Why energy is quantized in quantum well?
Why energy is quantized in quantum well? Charge transfer occurs leading to a conducting channel within single quantum well or multiple quantum well. The energies of the electrons are quantized in the step like density of states. Therefore many carriers can be put in the channel with a narrower dispersion of energies. Is quantum tunneling […]
