So in this case when a dc supply applies to it, the regulated DC voltage will switch the frequency oscillator ic and the MOSFET 's will function the push-pull amplification. This will use a transformer to produce the required power output. Therefore we can get a normal inverter DC/AC output. To make this output a pure sine wave, there is a filter circuit fixed at the output the AC terminal. Therefore it will filter the unnecessary frequencies, harmonics and will produce a constant pure sine wave.
Some lamps only need a simple resistor to control power. LEDs need a low power resistor for current control. The resistor is not acceptable for larger power lamps because it creates a lot of waste heat and therefore reduces efficiency. Electronic ballasts usually change the frequency of power to a lamp from 50/60 Hz to 20 kHz+. Electronic ballasts are usually viewed as being more efficient because by running a lamp at a higher frequency you get more efficacy or brightness from the lamp above 10 kHz.
In supercapacitor charge does not accumulate between two conductors, but in between surface of conductor and electrolyte. The capacitance value of an electrochemical capacitor is determined by two storage principles, both of which contribute to total capacitance value of capacitor. Supercapacitor bridges gap between conventional capacitors and rechargeable batteries. They have the highest available capacitance values per unit volume and greatest energy density of all capacitors
With a smaller need of gasoline, the mining of fossil fuels could be reduced thus preventing from the nonstop execution of our minerals. Besides, hybrid cars also can reduce current pollution as they emit less harmful and toxic gaseous from the exhaust. Miller(2004) claimed that hybrid cars also produce low sound which means less noise compared to the regular combustion engine cars. Engineers use electrical motors as they meant to work with a low sound. Moreover, in terms of energy, hybrid cars have higher efficiency compared to conventional and full electric cars as it uses kinetic energy from braking to form electric energy then, charging the battery simultaneously.
Early measuring instrument for small electric currents consisted of coil of insulated copper wire wound on a circular non-magnetic frame. Working based on the principle of the tangent law of magnetism. Galvanometer works on the principle of conversion of electrical energy into mechanical energy. When the current flows in a magnetic torque. Galvanometer has a word called sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from a mirror.
It appears that the diagrams do agree with my understanding of the concept of equipotential and electric fields. For both of the maps, the electric field lines are closer in the middle, which means that the electric fields are stronger in the middle. Most of the voltages have similar electric potentials, which explains that no work is done. Since no work done is being done on these field lines and the equipotential lines should be perpendicular to the electric field lines. However, it appears to be slightly off from what should be expected, and this may be caused by some sources of
By applying DC power supply to a TEC, heat will be transferred from one side of the conductor to the other. It creates a cold and a hot side. They are widely used in industrial areas, for example, computer CPU, Servers, portable refrigerator, medical instruments, and so on. voltage, it is also desirable in a precision temperature control to take advantage of this heat/cool capability. Thermoelectric coolers operate by the Peltier effect (which also goes by name thermoelectric effect).
In comparison with other conventional technologies, membrane distillation benefits from low operational temperature and pressure and therefore low energy requirements. In this process a lower energy is required due to working temperatures below the feed normal boiling point, so waste heats or other alternative energies including geothermal and solar energy are also applicable[7–10]. In addition, since there is no need to apply pressure difference between two sides of the membrane, membrane fouling as one of the most serious problems in pressure-driven membrane processes is less significant. The membranes in MD process are required to have hydrophobic properties i.e. low surface energies.
MR fluids require small voltages and current, while ER fluids require very large voltage and very small currents. According to the experts, MR fluids have become a widely studied “smart” fluid due to its less consumption of energy. The fluid that is transferring from top to bottom or from bottom to top must pass through the MR valve. The MR valve is fixed size orifice with ability to apply a magnetic field to the orifice volume. This magnetic field changes the viscosity of MR fluid, which will cause change in flow rate.
The thermocouples used in the experimental setup are T type thermocouples. The radiators wall temperature is measured using these thermocouples. Flow meter is also included in the setup to measure and control the motion. Here a vibrator heater is used to replicate the heat emission of any automotive engine. A DC power supply is used to run the fan instead of a car battery.
