What is a Thermistor? A thermistor is defined as a type of resistor whose electrical resistance varies with temperature changes. Although the resistance of all resistors will slightly fluctuate …
Potentiometer What is a Potentiometer? A potentiometer is defined as a 3 terminal variable resistor in which the resistance is varied manually to control the current flow. How Does …
Valence electrons Valence electrons are the electrons found in outermost shell surrounding an atomic nucleus. Valence electrons are important because they provide a deep insight into the chemical properties …
Coulomb’s law Coulomb’s Law gives an idea of the force between charges at two points. By the word point charge, we mean the size of linear charged bodies in …
Ionization energy The energy needed to remove an electron from a gaseous atom or ion is called ionization energy. An atom or molecule’s first or initial ionizing energy or …
Capacitor is an element that stores electrical charge. The capacitor consists of two close conductors (usually plates) separated by a dielectric surface. Once attached to the power source, the …
Transistor as an amplifier Both types of transistor amplifiers operate using AC signal inputs that vary between a positive value and a negative value in order to allow a …
Transistor as a switch The transistors Base biasing voltage is applied when used as an AC signal amplifier in such a way that it always operates within its “active” …
Transistor Definition- Transistors amplify current, the small output current from a logic IC can be amplified so that a light, relay or other high-current system can be controlled. A …
Georg Simon Ohm has found the nature of electrically conductive materials to oppose the flow of electrical current through them and it is named as resistor. To indicate the …
