In this case the word negative means earth or "chassis of a car" and we commonly refer to this as "negative earth" or "negative chassis." In the second diagram, the output from a power supply has a positive 12 ... 555 Timer IC Testing Circuit and Its Working Electronics Hub A Brief Note on 555 Timer IC I won’t go into the details about the 555 Timer IC but a few important things you need to need before understanding how the 555 Timer IC Testing Circuit works. Transistor 101science 2. TYPICAL TRANSISTOR CIRCUIT This is a silicon transistor circuit showing typical voltage values.When the forward base emitter voltage is 0.6 to 0.7 V, the transistor is silicon. Germanium transistors will have a forward base emitter bias voltage of 0.2 to 0.3 V This is a silicon transistor because 2.6 base volts minus 1.9 emitter volts equal a forward bias of 0.7 volts indicating a silicon ... cdselectronics 12 V BATTERY TESTER. INSTRUCTION SHEET . Price Stock No 550. Description. This kit measures battery voltage. The red LED (closest to the IC) indicates a low status 11.5Volts or less. Building the K7QO Noise Source (Manhattan Style) In an earlier post, I had need for a noise source to evaluate a circuit in the MMR 40 40 meter transceiver. I had chosen the K7QO design that was based on an RSGB circuit. On that occassion, I had built it on a breadboard, and modified it to work down to audio frequencies. 4QD TEC: Electronics Circuits Reference Archive Index 4QD TEC: Electronics Circuits Reference Archive.

Bowden's Hobby Circuits owden's Hobby Circuits. A small collection of electronic circuits for the hobbyist or student. Site includes 100 circuit diagrams with text descriptions, several electronic calculators, links to related sites, commercial kits and projects, newsgroups, and educational areas. Frank's LED Microscope Transistor T 2 controls the LED. Together with R 3 it is in series with the LED. That means that the LED current also flows through the transistor and the resistor. Parallel to the resistor is the BE path of the transistor T 1.Because the BE voltage drop of a transistor is always 0.7 V also the voltage across the resistor is fixed to 0.7 V. 0 28V 6 8A Power Supply (LM317, 2N3055) Electronics DIY This is an easy to make power supply which has stable, clean and regulator 0 28V 6 8 Amp output voltage. By using two 2N3055 transistors we become more then 2 times the amount of amps then the power supply delivers, making it real though to brake ;).
