Zener Diode Tester Circuit electroschematics The zener tester circuit is a simple dc dc boost converter designed around the most common IC – the 555 chip. The 555 IC (U1) is wired as an astable oscillator at a frequency (around 68KHz) determined by RC components (R1, R2 and C1). Diode at AC compressor | Heavy Equipment Forums There are various types of diodes, triodes, and quadrodes, but it is likely a Zener Diode. A regular diode is a one way valve only. A Zener diode is a DC voltage dependent valve . Syllabus for T.G.T.(W.E.) ELECTRO SCIENCE CLUB Syllabus for written examination of Work Experience Teacher (Electrical Gadget and Electronics) Fuse (electrical) A miniature time delay 250 V fuse that will interrupt a 0.3 A current at after 100 s, or a 15 A current in 0.1 s. 32 mm (1 1 4") long. 50 555 Circuits Talking Electronics WARNING!! Before making any 555 project, remember the chip takes about 10mA ALL THE TIME and cannot be turned off. The output (the "driving power") of a 555 is about 200mA while the CMOS versions are only about 50mA. Testing Electronic ponents MEASURING VOLTAGE Most of the readings you will take with a multimeter will be VOLTAGE readings. Before taking a reading, you should select the highest range and if the needle does not move up scale (to the right), you can select another range.
