EDUCATION Lecture Notes - Lecture 4: Variable Capacitor, Semiconductor Device, Diode
Document Summary
Tools are very important because a particular task can be done by using them. Schematic diagram shows the interconnection of components in the circuit: draw the symbol of the following, diode, pnp transistor, variable capacitor. Resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. It is a device that limits or resists current: determine the resistance value of a resistor having the colors yellow, violet, orange, gold. 28: determine the equivalent or total resistance of the four identical resistors connected in parallel. (resistor"s value is 100 each), using the resistor color code, determine the resistance value of a resistor having color bands brown, black, red respectively. Hint: use 1st band, 2nd band and multiplier only). Exercises iii: differentiate between an intrinsic semiconductor and an extrinsic semiconductor. Every atom in the crystal is a silicon atom, while extrinsic semiconductor is a doped semiconductor.
