Voltage

When a DC voltage is supplied to the coil it induces a current flow through the coil. The electric current and the magnetic field will therefore interact resulting to a force, which pushes the coil to move in its direction. Figure 2: Torque production in a DC…

concentrated inside the cell and sodium is more concentrated outside the cell. 2. Resting membrane potential is the difference in voltage of the fluids inside a cell and outside a cell. It is measured by the difference in voltage inside and outside of the cell. 3. On the outside of the resting membrane potential it would remain at 0, however on the inside it dropped the voltage from -70 to -40. This happened because with the increase of K+, there was more K+ to pass through the leak channels,…

nerve signal. The nerve signal must be sent to the neuromuscular junction to open the voltage-gated calcium channels. Just like in a muscle fiber, the neuron must reach threshold potential before the action potentials can be propagated down the neuron. After the threshold potential is reached, voltage-gated sodium channels open causing sodium to rapidly move into the cell. This is called depolarization because voltage inside the cell becomes more positive (there is less of a difference in charge…

For example, if you have a resistor with a resistance of 3 ohms and the current at it being 1 amp the voltage drop at that resistor is 3 volts (3*1). If you have more than one resistor wired to that circuit you can check your math by adding all the voltage drops at the resistor together, the sum should equal to the voltage of the power source or battery. Parallel DC circuits differ from DC series circuits mainly in the way they are wired to their components. As…

and measure the electrical voltage produced when the magnet passes through a coil of wire. Our dependent variables were the amount of magnets (length of magnet) and the amount of shakes. This was done to help us discover if there was a relation between the amount of magnets, and the induced current produced. It was to investigate if a greater magnetic field and increased amount shakes would improve the shake torches ability to light the LED faster by producing more voltage. This was what was…

is modified to suit the needs The x-ray beam given off an x-ray tube may be changed to suit the needs of the use by changing the following: Tube Voltage (kVp): The alteration of tube voltage affects both quality & intensity. It affects quality because of the maximum photon energy that is determined by the tube voltage. Thus, the higher the tube voltage,…

Membrane Potential in the RMP The membrane potential in the Resting Membrane Potential, or the RMP, is the little bit of voltage or electrical potential going across from the membrane of its regular resting voltage. This is caused because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their…

Abstract –– The large increase in load demands cause congestion in transmission lines which leads to instability in the power system operation. Distributed generation is used to minimize the power losses and thus to improve the system stability. Improper DG placement may increase system losses, network capital and operating costs. Which is important to find the size and location of distributed generation, inorder to minimize line losses of power system. This paper uses the Maximum Power…

The way that Stanley Milgram went about his experiment was unethical. It put the teachers in a position to have to harm someone. The teachers could choose the voltage used in the shock chair but it had to be at least 15 volts. It is not morally right to give someone no other choice than to harm someone else. The First Study Milgram was studying how punishing someone can affect their learning. His experiment included a teacher that was a male recruit, a learner who was associated with Milgram,…

thickness of piezoelectric element, voltage, and input frequency. The simulation results showed that the displacement of the vibrating diaphragm increased with applied voltage. Moreover, when the piezoelectric thickness was increased, vibrating diaphragm displacement also was decreased. The flow rate can be adjusted by increasing or decreasing of the input voltage. Presented results also showed that the performance of the micropump was affected by the frequency of voltage. In this study, we…
