The resonant frequency f = 1/SQRT(L *C) For a parallel LC circuit, the equivalent total Reactance is. Xt = 1 / (1/jXC) + (1/jXL) which in turn is. Xt = (jXL * jXC) / (jXL + jXC)

Impedance (symbol Z) is a measure of the overall opposition of a circuit to current, in other words: how much the circuit impedes the flow of current. It is like resistance, but it
