1. The problem statement, all variables and given/known data 10 v, 100 hz goes into a circuit of a 1o resistor, a 1o inductive reactance and a 1o capacitive reactance that are in series. What is the current. What is the V across the cap. 2. Relevant equations and the attempt at a solution So I know I = V/Z and Z = sqrt( R^2 + (XL^2 - XC^2 ) And the question gives us the inductive reactance and capacitive reactance which is XL = 1 and XC = 1, and it gives us R = 1 So now, Z = sqrt(1^2 + (1^2 - 1^2 ) ) = 1 And I = V/Z = 10/1 = 10 A Is that correct for the current of the circuit? If so, how do I calculate the voltage across the capacitor? Is it voltage of capacitor, Vc = I * XC = 10 * 1 = 10 V ? Is that correct?
