) of a resistor is R in rectangular form and R / 0o in angle form.

[10] 1. 14.

The two quantities are in phase.

. Ohm’s Law for AC circuits: E = IZ ; I = E/Z ; Z = E/I. 1.

Pure resistive AC circuit: voltage and current are in phase.

We do the same thing here, only we add them as vectors, and we call the equivalent resistance the impedance of the circuit and give. L - ideal inductor. Figure 23.

resistor, a 3. Inductors store energy in the magnetic field.

In this chapter, we will explore RC circuits, which consist of resistors (R) and capacitors (C).

Capacitive reactance can be calculated using this formula: XC = 1/ (2πfC) Capacitive reactance decreases with increasing frequency.

11 Example 1 and Chapter 23. Here, too, energy is continually being stored and then.

. Use phasors to understand the phase angle of a resistor, capacitor, and inductor ac circuit and to understand what that phase angle means.

Series capacitor circuit: voltage lags current by 0o to 90o.

0 Hz and 10. Plots of i R ( t) and v R ( t) are shown in Figure 15. Series capacitor circuit: voltage lags current by 0o to 90o.

. 1. Figure 15. Therefore, the total capacitance will be lower than the capacitance of any single capacitor in the circuit. .


class=" fc-falcon">Calculating Impedance and Current. The combined effect of resistance R, inductive reactance X L, and capacitive reactance X C is defined to be impedance, an AC analogue to resistance in a DC circuit.

Initially, there is no current in the circuit.

4: RLC Series Circuits with AC.

The phase relation of these components can be stated as follows: The instantaneous voltage over the resistor is in phase with the instantaneous current.

Calculate the total.
