Light-transducing proteins are not present in the Pacinian corpuscle. 77. Why do you think TTX is not used during dental procedures? TTX irreversibly blocks voltage-gated sodium channels in axonal membranes. Why is it harder to generate a second action potential during the relative refractory period? A greater stimulus is required because voltage-gated K+ channels that oppose depolarization are open during this time. Why is the action potential recorded by the second recording electrode (R2) delayed

Construction Digital Voltmeter Raj K. Gorkhali A voltmeter finds its importance wherever voltage is to be measured. Here we present an easyto-build and accurate digital voltmeter that has been designed as a panel meter and can be used in DC power supplies panels or where it is necessary to have an accurate indication of the voltage. Circuit description The circuit uses an analogue-todigital converter ICL7107 made by INTERSIL. Fig. 1 shows the pin detail of IC L7107. This IC incorporates in

directly proportional to the output voltage and output current of the proposed DC motor driver‚ respectively. 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

is a semiconductor device that controls current between two terminals based on the current or voltage at a third terminal. It is used for amplification or switching of electrical signals. The basic structure of the bipolar junction transistor‚ BJT‚ determines its operating characteristics. DC bias is important to the operation of transistors in terms of setting up proper currents and voltages in a transistor circuit. Two important parameters are αDC and βDC Electronics Fundamentals

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
