instruments were very useful in the basic study regarding the course‚ and in expanding my knowledge about these devices. I learned that the resistors can be classified as fixed and varying which are respectively adjustable and non-adjustable. The capacitors have only one charge beginning with the positive half cycle and ending with the negative or vice-versa. I also learned the features that can be done by the function generator and the oscilloscopes. Every controls on the scope are essential un

one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching‚ because then we would only have a conductor. The insulator between the plates is also known as the dialectic‚ which affect how the capacitor will store charge. In an RC circuit‚ voltage will flow from the battery to the capacitor and through the resistor. When the capacitor is charging‚ the voltage across

Laboratory No 4 Electrical Systems 100 AC CIRCUITS INTRODUCTION The purpose of this laboratory test was to make comparisons between theoretical and practical results and to develop a greater understanding of factors affecting the operation of complex AC networks. SUMMARY OF RESULTS The error in the results ranges from 0.02% to 22.63% and the phase angle errors ranged from 0.02° to 17.27°. This suggests that part of our results were very accurate (series parallel RC network) and the rest

state estimation based protection‚ all existing measurements in the protection zone are utilized. These measurements include: currents and voltages at the terminals of the protection zone‚ currents and voltages inside the protection zone (as in capacitor bank protection)‚ speed and torque (as in rotating machinery)‚ or other internal measurements including thermal measurement. All above measurements should obey the physical laws for the protection zone (physical laws such as KCL‚ KVL‚ motion laws

up of ferromagnetic (iron) material magnetizes and experiences a force towards the center of the electromagnetic coil (solenoid). A large current is forced through the coil‚ creating a magnetic field and attracting the ferromagnetic projectile. Capacitors are charged up over a few seconds‚ and then all of their electrical energy is released extremely fast. In an EFPA the energy is released into a coil of wire. This creates a powerful magnetic field which causes any ferromagnetic object in the coil

Within this experiment we recorded that the theoretical capacitance of 0.470 is accurate with the capacitor from box C. The LRC circuit is proven to have a voltage accurate with the measured generator voltage because the largest percentage of error ‚ 0.55 % error‚ is much lower than 5% error. Summary The idea of the alternating current RC and LRC circuits lab is to record the value of a capacitor in an RC circuit by using their phase relationship in the equation VT2 = VC2 +VR2 to determine a
