What if there was no internal resistance? When there is a negligible internal resistance, the p.d. across Y will equal the emf of the cell. As the p.d. is now constant and the relationship between power and resistance, for a constant voltage is inverse, the power would decrease as the value of Y increases. What […]

What are secret key algorithms?
What are secret key algorithms? A secret key algorithm (sometimes called a symmetric algorithm) is a cryptographic algorithm that uses the same key to encrypt and decrypt data. A very simple example of how a secret key algorithm might work might be substituting the letter in the alphabet prior to the target letter for each […]
Would a plant grow well in green light?
Would a plant grow well in green light? Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture. Sometimes one may hear that plants don’t use green light for photosynthesis, they reflect it. However, this is only partly true. What […]
