View Solution A resistor and a capacitor are connected to an ac supply of 200 V, 50 Hz, in series. The current in the circuit is 2A. If the power consumed in the circuit is 100 W then the resistance in the circuit is View Solution ...
individual capacitor in the series. It should be noted that for practical purposes, capacitive voltage dividers are only useful in AC circuits, since capacitors do not pass DC signals, and also because they have a certain voltage leakage. The following figure illustrates the capacitive voltage ...
For the DC applications, an ad hoc circuit is necessary for the use of SCR, this is important to force the device into turn off state. However, the SCR application in DC systems is not further developed in this paper as it focuses only on AC applications. Figure 4. The AC “Back to...
A pure resistive circuit element X when connected to an AC supply of peak voltage 200 V gives a peak current of 5A. A second current element Y when connected to same AC supply gives the same value of peak current but the current lags behind by 90∘. If series combination of X and ...
When a resistor is used in an AC circuit, the variations of the current through and the voltage across the resistor are in phase. In other words, their sinusoidal voltages and currents have the same phase. This in phase relationship can be analyzed using the generalized Ohm’s law for the...
