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

varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (EMF)‚ or "voltage"‚ in the secondary winding In electrical engineering‚ two conductors are referred to as mutual-inductively coupled or magnetically coupled [1] when they are configured such that change in current flow through one wire induces a voltage across the ends of the other wire through electromagnetic induction. The amount of inductive coupling between two conductors is measured

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

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
