Blades of the fan undergo circular motion. Fan undergoes the rotational motion as it rotates on its own axis. Visit BYJU'S - The Learning App to... View Article
The NPN transistor is constructed in a way such that the electrons from the emitter is transferred to the collector. The emitter emits the... View Article
Adsorption is a spontaneous process that is carried out by a decrease in the free energy of the system. When Gibbs free energy (ΔG) becomes zero,... View Article
Enthalpy is the energy-related to P, V and T. Hence, if T changes when the heat is transferred but if P changes as in the case of a nozzle,... View Article
As we move down the group, the lattice energy decreases. This is due to the fact that with the increase in the size of ions, the distance between... View Article
The enthalpy is positive in case of an endothermic reaction where the energy is taken from the surroundings. In case of an exothermic reaction,... View Article
Yes, transistors are semiconductor devices that are used to amplify or switch electronic signals. Transistors consist of three terminals, and... View Article
A transistor is a three-terminal semiconducting device. By applying input current/voltage to one pair of terminals, there is a change in the... View Article
The second law states that the entropy in a closed system always increases. As an example, let us consider the growth of a leaf. The leaf... View Article
The second law of thermodynamics states that the entropy of a closed system will always increase with time. The only known closed system is the... View Article
The freezing of water doesn’t violate the second law of thermodynamics. However, the ice is more ordered and has lower entropy. But, the energy... View Article
Throttling is a process where a high-pressure fluid is converted into low-pressure by using a throttle valve. In a throttling process, the... View Article
Transistors are semiconductor devices with at least three terminals. The CE or common emitter connection is one of the widely used configurations... View Article
Inductors store the supplied electrical energy in the form of magnetic energy. It does not allow AC to flow through it but allows DC to flow... View Article
