How do you find power input with given power factor and power output?
Output Power divided by Power Factor.
How Determine the power dissipated by the resistor?
Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor. You need to measure or find the information of either I (using an ammeter) or V (a voltmeter).
Where can one find information on electric heating systems?
Wikipedia have information on electric heating systems including the types of heating systems that are available. One can also find information on 'Which' including the costs and advantages of these heating systems.
What is power factor in an electrical power system?
In an alternating current system, the voltage and current may or may not rise and fall at the same time. In resistive circuits it does but the current in other cases may lead or lag the voltage. For a single phase system Power = Power Factor * V * I The power factor is the cosine of the angle between V and I and is a maximum (1) in resistive circuits.
Unit step signal is energy or power signal?
The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.
