Homework Statement
a resistor, a capacitor and an inductor are connected in parallel to a source of oscillating EMF of frequency 955hz and amplitude of 1.0x10^3 V. the resistance of the resistor is 200Ω. what is the maximal instantaneous current in the resistor? if we want to make a maximum instantaneous currents in the capacitor and in the inductor equal to that in the resistor, what values of the capacitance and the inductance must we select?
Homework Equations
Irms= ΔVrms/(R^2+(xl-xc)^2)^(1/2)
Irms= Imax/(2)^(1/2)= 0.707Imax
xl=wl
xc=1/wc
frequency= 955hz (2∏f)
The Attempt at a Solution
amplitude is given, therefore, we can consider this Vmax
Irms= 1.0x10^3V/ (200^2+(xl-xc)^2)^(1/2)
