These same fruits and vegetables also contain a large amount of water. The water in all fruits and vegetables makes them good conductors of electricity. Other ingredients such as citric acid and ascorbic acid increase the conductivity‚ creating more voltage Vegetable Electricity Conductors Potatoes‚ onions and tomatoes are all good vegetable conductors. Tomatoes are most likely the best vegetable conductor since they have the highest acidity level. Fruit Electricity Conductors Some good fruit electricity

Abhishek Akkeneni 902667190 INTRODUCTION – WHAT ARE OPERATIONAL AMPLIFIERS? An operational amplifier ("op-amp") is a DC-coupled high-gain electronic voltage amplifier with a differential input and‚ usually‚ a single-ended output. An op-amp produces an output voltage that is typically hundreds of thousands of times larger than the voltage difference between its input terminals.[1] Op-amps are among the most widely used electronic devices today‚ being used in a vast array of consumer‚ industrial

LDR will be very less. Here 555 timer IC is configured as a monostable multivibrator. The LDR will trigger the 555 timer. The output of the 555 timer IC is directly fed to the baser of the transistor. This gives low signal and it turns ON the coil voltage of the relay. Street lights were connected to relay.

of light depends on the energy gap of the semiconductor. Avalanche Diode: This type of diode operates in the reverse bias‚ and used avalanche effect for its operation. The avalanche breakdown takes place across the entire PN junction‚ when the voltage drop is constant and is independent of current. Generally‚ the avalanche diode is used for photo-detection‚ wherein high levels of sensitivity can be obtained by the avalanche process. Laser Diode: This type of diode is different from the LED type

Adaptive controlling of the output voltage and current are possible by installing algorithm in the microcontroller of the DC motor driver and it can be reprogrammed according to the requirement. The speed control makes the solar tracking system to track the Sun more accurately and the torque control saves energy. converter is used to step down the voltage in order to reduce the turning speed

THE WAR OF CURRENTS Tesla vs Edison: THE WAR OF CURRENTS In the "War of Currents" era (sometimes "War of the Currents" or "Battle of Currents") in the late 1880s‚ George Westinghouse and Thomas Edison became adversaries due to Edison’s promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by Westinghouse and Nikola Tesla. Thomas Edison American inventor andbusinessman was known as "The Wizard of Menlo Park" and pushed

Adrian R. Managbanag BSESE 2B Kirchhoff’s Circuit Law Kirchhoff’s circuit laws are two approximate equalities that deal with the current and voltage in electrical circuits. They were first described in 1845 by Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of Maxwell. Widely used in electrical engineering‚ they are also called Kirchhoff’s rules or simply Kirchhoff’s laws (see also Kirchhoff’s laws for other meanings of that term). Both of Kirchhoff’s laws can
