EXPLAIN WHY SIMULATION IS NEEDED!
ANSWER: BECAUSE SIMULATION NEEDS TO BE DONE
explain why simulation is needed! Answer: Because the simulation needs to be done before the actual situation occurs to reduce the effects of these events and to do a series of trials to estimate the behavior of the system over a certain period of time. 2. Explain each of the NPN diode and transistor characteristic curves you get! Answer: – Diode ＝ To be able to clarify the working principle of a diode in delivering and inhibiting electric current. – NPN transistor ＝ Collector-Emitter diode graphic commonly known as a voltage-current curve (V-1 Curve). This curve depicts Collector Ic current, with the Collector-Emitter Vce cross-link voltage, where the prices are measured by base current Ib, which varies. 3. Compare the simulation results with the experimental results! Answer: – Simulation proses a process of imitation of a real series that describes the situation around him. – Experiment ＝ a process of action and observation to make a series that has been simulated. 4. Explain why the experiments carried out in figures 7c and 7d, while pictures 7a and 7b did not! Answer: Because in Figures 7a and 7b is a series of simulations that will be done while Figures 7c and 7d is a series of experiments that resemble the previous simulation drawing. 5. Explain the working priodes of diodes and transistors! Answer: – Diode ＝ Maximizes alternating electric current. With the alternating current passed to the diode, the performance of the electrical equipment will be maximal. – Transistor ＝ Transistor as amplifier and Salar transistor. At the base of the transistor is given a bias voltage then the current in the transistor collector will flow to the emitter’s foot (the transistor as a switch). 6. (Optional) Explain the application of diodes and transistors! Answer: – Diode ＝ Application of a diode as a rectifier AC voltage or rectifier is the basic circuit of a power supply that is most widely used in almost all electronic circuits. There are a number of variations of the diode rectifier, each of which has a different output signal characteristic. – Transistors ＝ Transistors can function like an electric faucet, which based on the input current (BJT) or the input voltage (FET), allows a very accurate flow of electricity from the mains circuit. Transistors are used in amplifiers. Analog circuits surround loudspeakers, stable power sources (stabilizers) and radio signal amplifiers. In digital circuits, transistors are used as high-speed switches. 7. (Optional) Mention and explain the types of diodes and transistors! Answer: 1. Diodes • Normal diodes ＝ diodes most commonly found in electronic circuits, especially in power supply circuits and radio frequency circuits (RF) • Bridge diodes ＝ diodes consisting of 4 normal diodes which are generally used as rectifiers full wave in the power supply circuit (power supply). • Zener diode ＝ special type of diode designed to operate in a reverse bias circuit • LED diode ＝ type of diode that can emit monochromatic light when applied forward voltage • photo diode ＝ type of diode that can change light energy into an electric current. • Laser diode – a type of diode that can produce radiation or coherent light that can be seen by the eye and infrared spectrum when electrified. • Varactor diode ＝ type of diode which has the capacity of the capacity changes according to the applied voltage. • Diode Tunel ＝ type of diode that is able to operate at very high speeds and can function well on microwaves (microwave) • Schottky diodes ＝ type of diode with a lower forward voltage than normal diodes in general. 2. TRANSISTORS • Bipolar Junction Transistors – transistors built from 3 regions, base, collector, and emitter. • NPN transistor ＝ one where the majority of current carriers are elktron • PNP transistor mayoritas majority current carriers are holes • FET transistor ＝ consists of 3 gate, source and drain regions, voltage controlled devices. • Bipolar Heteronjunction Transistors ＝ for digital and analog microwave applications with frequencies as high as ku band • Darlington Transistors transistor transistor circuits made of 2 transistors • Schottky transistors ＝ a combination of transistors and schottky diodes that prevent transistors from saturating by diverting extreme input currents • Multi-transistor transistors Emitter ＝ specialist bipolar transistor which is often used as an input transistor logic transistor (TTL)
