shortening its life. 6. Plot the same waveforms for the circuit built on the thyristor instead of the diode. 7. List the advantages and disadvantages of these devices. Easy to destroy the device by too high voltage, current or frequency values Large currents cause significant voltage drops It can convert alternating current/voltage into direct one Can be applied in detectors, which fin signal in noisy condtitions Used as a switch also, ideal rectifier acts like a switch that closes the current flow when foward biased and opens it when reverese biased Round the true answers 1. What is resistance of metal due to? voltage current ionization vibration 2. What are the majority carriers in the base of an npn transistor? electrons holes protons neurons
