AC & Capacitors Does Kirchoffs Voltage Law apply to AC Circuits? V R =6.0V V C = 8.0VV s = 10.0V
AC & Capacitors Does Kirchoffs Voltage Law apply to AC Circuits? V R =6.0V V C = 8.0VV s = 10.0V YES! It DOES!!
Consider the graphs of the voltages of the components :
Consider the graphs of the 3 components voltages :
At Any Instant in time the Vs=Vr+Vc So Kirchhoffs Laws DO apply – its just that our voltages are out of phase with one another
Phase Relationship for Voltages in a R-L Circuit VRVR VCVC VCVC VRVR VSVS V R leads V c by º V C lags V S by (90- )º V S 2 = V c 2 + V R 2
Impedence (Z) The combined effect of resistance and reactance in a circuit. SI Unit: Ω V R =IR V C =IX c V s =IZSo Z 2 = R 2 + X c 2
Impedance Phasors can help us see the relationship for Impedance VCVC VRVR VSVS V S 2 = V C 2 + V R 2 V C = IX C V R = IR V S = IZ XCXC Z R Z 2 = X c 2 + R 2
Summary: Reactance: Voltage: Phase Difference: Impedance: V S 2 = V C 2 + V R 2 X C = 1/(2 ƒC) Z 2 = X C 2 + R 2 V R leads Vc
VSVS L C R At every instant, the generator / supply voltage: (V S = V m sinωt) is given by: V S = V L + V C + V R IZ = IX L + IX C + IR These relationships.
RLC Circuits. Ohm for AC An AC circuit is made up with components. Power source Resistors Capacitor Inductors Kirchhoff’s laws apply just like DC.
AC & Inductors In DC circuits an inductor limits current momentarily when: the circuit is first turned on and the current is increasing from zero to full.
