SUMMARY
The impedance (Z) in an RC circuit is calculated using the formula Z = sqrt[R^2 + (1/wc)^2]. To find the amplitude and phase of the current, one must express the impedance as a complex number rather than just its modulus. The voltage is given by V = E*cos(wt), and the current can be derived from I = V/Z, where Z includes the imaginary component due to the capacitive reactance (1/jwc). Understanding complex numbers is essential for this analysis.
