Electronics engineering reference online- electrical formulas, circuit theory and design guides, theorems, electricity and magnetism basics. Calculation of impedances of series basic electrical engineering formulas pdf parallel circuits. I-V characteristics for transistors and diodes.
Let’s start with quick definitions. The term “circuit” refers to a collection of components through which electrical current can flow or which use electromagnetic fields in their operation. Here you will find electricity and magnetism reference, basic electrical engineering formulas, calculators, and other related information. The properties of semiconductor devices are studied in college courses.
Below are just some highlights. Vin- the supply voltage, Z- net impedance in the external collector circuit. When Ic reaches the above limit, the transistor is saturated. Once Id reaches certain limit determined by an external circuit, MOSFET start acting as a nearly constant resistance.
