The transfer of heat through electromagnetic energy is known as radiation. The heat that we feel when we stand next to a fire is the heat... View Article
No, we don’t prefer to use a Zener Diode in a rectifier circuit because for a rectifier circuit a high maximum peak inverse voltage is required.... View Article
Sound waves are produced by a source such as the vibrating diaphragm of stereo speakers. The sound source creates vibrations in the surrounding... View Article
Young’s modulus sometimes referred to as modulus of elasticity measures the ability of the material to withstand changes in length when under... View Article
Light behaves both as a particle and a wave. Light has a dual nature: Sometimes it behaves like a particle (photons) which explains why light... View Article
The buoyant force is the upward force of the rising water exerted upon the object by the fluid. The fluid pressure increases as the object's... View Article
The nodes in the circuit help us determine if the connected resistors are in series or parallel. A node in a circuit is a point of connection... View Article
No, S waves are slower than P waves. Both S waves and P waves are body waves that propagate through the Earth’s interior. On average, P waves... View Article
A transistor is a semiconductor device that amplifies electronic signals and electric power. Transistors amplify and control the applied electric... View Article
Any scalars that are defined as the magnitude of a vector is non-negative. But, there are some scalars that can be negative. Electric charge is... View Article
A capacitor is an electronic component that stores electric charge. A capacitor consists of two closely placed conductor plates separated by a... View Article
Unbiased condition is when there is no external energy source. In an unbiased diode, the electric field is set up across the depletion layer... View Article
