The Delta H (enthalpy) of a chemical reaction can either be positive or negative. If the Delta H of a reaction is positive, then the chemcial... View Article
The tension in a pendulum is known to be perpendicular to the motion of the bob. Therefore, the tension does not do any work on the bob of the... View Article
When the bob of a pendulum moves back and forth, the type of motion involved is generally reffered to as "oscillation." The position of the... View Article
A pendulum can lose energy to the wind resistance, the friction between the tube and the string, or to the internal friction within the bending string.... View Article
Vinegar, by itself, cannot be reffered to as a solute. Moreover, vinegar is a solution of acetic acid in water. Here, acetic acid is the solute... View Article
Einstien's special theory of relativity suggests that only the particles having zero rest mass have the ability to travel at the speed of light.... View Article
A delocalized bond can be thought of as a chemical bond that appears in some resonance structures of the molecule, but not in others. The... View Article
The electrons of an sp3 hybridized atom are known to be farther from the nucleus than those in sp2 hybridized species. Therefore, sp2 hybrid... View Article
O22- is known to be diamagnetic. This is because there are no unpaired electrons in O22-. In contrast, both O2 and O2- are paramagnetic... View Article
If a product is removed from a system in chemical equilibrium, the equilibrium will shift to make more product in order to make up for the loss... View Article
Friedel crafts acylation is preferred over Friedel Crafts alkylation because in Friedel craft acylation, there is an oxygen with a double bond... View Article

In a diode, anode is the positive side and cathode is the negative side. Stay tuned with BYJU’S to learn more about other concepts such as what... View Article
The width of depletion layer in forward bias decreases. Stay tuned with BYJU’S to learn more about other concepts such as pn junction diode.... View Article
When the diode is forward biased it is equal to the flow of electrons through the diode. Stay tuned with BYJU’S to learn more about other... View Article
When a diode is shorted, the voltage drop reading in both the directions will be the same. Stay tuned with BYJU’S to learn more about other... View Article
When the forward current is excessive and the reverse voltage is large, then these could be the causes for a diode to go bad. Stay tuned with... View Article
