Voltage Dependent Resistor
A resistor and a capacitor in an AC circuit part of series 2?
Resistance to resistance R and capacitor C are connected in series to a source of AC power. The voltage versus time across the capacitor is given by V_C (t) = sin V_c_0 (omega * t). B) What V_r is the amplitude of the voltage in the resistance? Express your answer in terms of V_C_0, C, Omega, and R. =???? V_r
Instead of solving the problem domain of time, we will solve in the frequency domain using the arithmetic of complex numbers. If we do this, we redesigned the problem that Vc (ω) = I see with the voltage across the capacitor to determine our phase reference - not really need to explicitly follow the phase, we are asked only amplitudes. In all cases, the current through the capacitor is given by I (ω) = Vc (ω) / Zc (ω), but a capacitor, Zc (ω) = JXC (ω), where Zc (ω) is the impedance (complex) of the capacitor to the angular frequency ω, j = √ -1 (engineers j electricians prefer to use this constant instead of i, and the Convention for i be a variable name for the stream was created before arithmetic complex began to be applied to the problem.) and Xc (ω) is the reactance (negative real) of an ideal capacitor in the angular frequency ω, which is -1/ωC. The current through the capacitor, which is the same as the current in the circuit as a whole, because we are talking about a series circuit is to know why (ω) = VCO / (-j/ωC) = The jωCVco stress resistance is r (ω) = I (ω) Zr (ω) = I (ω) = R and jωRCVco | r (ω) | = ωRCVco If you want blood over time, will be r (t) = cos ωRCVco (omega.t) or sin ωRCVco (omega.t + Π / 2)
