A 1.5 megaohm resistor is connected across a voltage source of 120 volts DC. What is the power drawn to the resistor? 22. A SSB transmitter produced a maximum current of 1.5 amps and has a resistance of 153.33 ohms. Determine the peak envelop power. ...
The work is devoted to the development of an analytical method for calculating the reactive power and determining the location of the compensating devices from the position of the system functions of resistance. The importance of rational distribution of reactive power in electric networks is ...
It cannot be sold; though, it does waste power in the resistance of electric lines between load and generator. The parallel capacitor corrects this problem. Note that the reduction of line losses applies to the lines from the generator to the point where the power factor correction capacitor is...
The junction temperature Tjof the LDO regulator can be calculated as follows: where Rth(j-a)is the thermal resistance of the LDO regulator when it is mounted on a board. If Rth(j-a)is not shown in the datasheet, you can calculate it from the power dissipation (PD) val...
