In a resistor v and i are always out of phase

WebThese equations show that a series RC circuit has a time constant, usually denoted τ = RC being the time it takes the voltage across the component to either rise (across the capacitor) or fall (across the resistor) to within 1 e of its final value. That is, τ is the time it takes VC to reach V(1 − 1 e) and VR to reach V( 1 e) . Web(The phase angles of resistive and capacitive impedance are always 0° and -90°, respectively, regardless of the given phase angles for voltage or current.) As with the purely capacitive circuit, the current wave is leading the voltage wave (of the source), although this time the difference is 79.325° instead of a full 90°.

http://hyperphysics.phy-astr.gsu.edu/hbase/electric/phase.html WebIn a purely resistive circuit, all circuit power is dissipated by the resistor (s). Voltage and current are in phase with each other. In a purely reactive circuit, no circuit power is dissipated by the load (s). Rather, power is alternately absorbed from and returned to the AC source. Voltage and current are 90° out of phase with each other.

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
