PhET Simulation: This lab uses the Circuit Construction Kit AC simulation from PhET Interactive Simulations at University of Colorado Boulder. After launching the simulation, please select R-L-C window. Leave two significant figures in your calculated values. Theory: The capacitive reactance and the inductive reactance of a capacitor and an inductor, respectively, are defined as: Xc = 1/(WC) and XL =Wk, where w = 2Tif, is the angular frequency in rad/s, and f is the frequency in Hz. RC circuit and RL circuit. R R v(t)= Vo cos(wt) v(t)= Vo cos(wt) CIf the current in the R-C circuit is i(t) = /. cos(wt), then the maximum voltage across each element and the entire circuit is: VR = lexBe Kc= loka, and Vo = lez, where XR is simply the resistance R of the resistor, and Z = R2 + X- is the impedance of the circuit. The relation between the maximum voltage across each circuit component and the entire circuit is Vo = VR + V2 . (Eq.1) For an R-L circuit, similarly, the voltage across the elements and the entire circuit is: VR = lexBe VL = IXL, and Vo= lez, with the impedance of the circuit being Z = VR2 + x2. The relation between the voltages then is Vo = VUR + V2 . (Eq. 2) R-L-C circuit v(t)= Vo cos(wt) triangle Figure 3 In the case of a resistor, an inductor, and a capacitor connected in series to an AC source (R-L- C circuit), as shown on the diagram above, the impedance of the circuit is equal to: Z = R2 + (Xc - XL)2 . (Eq. 3) (for Xc > XL ) If the current in the circuit is given by i(t) = I. cos cos (wt) , the voltage across the circuit as a function of time is then given by v(t) = V. cos (wt+), where p is called a phase angle and for the RLC circuit above is equal to: tan (p) = 2c-XL R (Eq.4) Experimentally, the phase angle between the current and the voltage in the circuit can be determined by measuring the voltage value at the time when the current is zero. If the current i (t) = locos (wt ) = 0 at some time t,then cos(w) = 0 at that time. Using a trigonometric relation for cos (0+ [3), we can write the voltage v(t) as: v(t) = Vcos (mt + db) = V0 [cos (mt) cos (d3) sin (0.10517: (d))] When cos cos (mt) = 0 , then potential difference across RLC, v(t),v=o = Vocos (4:3) The phase angle (,6, then, can be determined as: (15 = arccos [1703,20] (Eq.5) Activity 1: Voltage across the elements in the RC circuit.
