 What is electron?

Electrons are negatively charged particles. They keep rotating in orbits inside the atom. They have a charge of 1.6 × 10^-19 coulomb. It is denoted by 'e'. To understand electrons, we need to understand the structure of an atom.



The diagram illustrates the structure of an atom, which consists of three fundamental particles: protons (p), neutrons (n), and electrons (e). Protons and neutrons reside at the center of the atom, forming the nucleus. Protons carry a positive charge (+ve), while neutrons are electrically neutral. Electrons, carrying negative charges, revolve around the nucleus in distinct orbits. The number of positive charges (protons) in an atom balances the number of negative charges (electrons), rendering the overall atom electrically neutral.

Electronics Components Devices

 Electronics Components Devices Electronic components form the building blocks of any electronic circuit. They come in various types, with some having two connection points (terminals) and others, like integrated circuits (ICs), having three. ICs, often used in surface-mount technology (SMT) and found in devices like mobile phones and computers, are just one example of the diverse components used in electronics. Generally, electronic components can be broadly categorized into two main types. (1) Passive components (2) Active components (1) Passive components - Passive components do not require an external power source to operate. Examples include resistors, capacitors, and inductors. These components are directly added to a circuit and function without needing additional power. However, unlike active components, passive components cannot amplify or process signals. (2) Active components - Active components require an external power source to function. Examples include diodes, transist

Digital Multimeter

Image
Digital Multimeter A digital multimeter is an electronic instrument used to measure the values of various electrical quantities, such as resistance, capacitance, and voltage. It can be used for both DC and AC. The multimeter has different sections for measuring each quantity, which can be set using the rotary knob. It also has a display to show the measured value. Two probes are provided to make contact with a component or PCB. Key Points A digital multimeter is an electronic instrument used to measure electrical quantities.

What is electrical Inductance ?

Image
 What is electrical Inductance ? Inductance is the property of a conductor that opposes changes in the current flowing through it. It is denoted by the symbol 'L'. When current flows through a coil of wire, a magnetic field is generated around the coil. This magnetic field creates a magnetic flux linked to the coil. Any change in this associated flux, whether due to a change in the current itself or other factors, induces an electromotive force (EMF) in the coil. Where, The induced electromotive force (EMF) generated in the coil opposes the change in the main current. This opposition to change is a characteristic property of inductors and is called inductance.
