WebApr 12, 2024 · The impedance of the resistor is simply its resistance, which is 1 kiloohm. The total impedance of the series circuit is the sum of the impedance of the capacitor and the resistor: Z_total = Z_c + R = -j15.92 + 1000 = 1000 – j15.92 ohms The magnitude of the voltage across the capacitor can be found using Ohm’s law: V_c = I × Z_c WebThe reason for this convention is so the signs of current and voltage come out right when we apply the defining equations for each component, like Ohm's Law for a resistor.

"WebSince the current and the voltage both depend on time in an ac circuit, the instantaneous power p (t) = i (t) v (t) p (t) = i (t) v (t) is also time dependent. A plot of p(t) for various circuit elements is shown in Figure 15.16. For a resistor, i(t) and v(t) are in phase and therefore always have the same sign (see Figure 15.5).

WebFeb 24, 2012 · In case of resistor, both voltage and current are in same phase. So draw the voltage phasor, V R along same axis or direction as that of current phasor. i.e V R is in phase with I. Step- III. We know that in inductor, voltage leads current by 90 o, so draw V L (voltage drop across inductor) perpendicular to current phasor. Step- IV.

WebIf they are “in-phase” that is, there is no phase shift then they can be added together in the same way as DC values to find the algebraic sum of the two vectors. For example, if two voltages of say 50 volts and 25 volts respectively are together “in-phase”, they will add or sum together to form one voltage of 75 volts (50 + 25). WebThe phrases "Voltage on" and "Voltage across" mean the same thing. One end of the resistor is at a higher potential than the other end. The difference in potential is called the "voltage across" the resistor. It is the nature of resistors that when they have a voltage across them, a current flows. When current flows, there is energy being ...
