Quizplus · Accepted Answer

The impedance of an LRC series circuit is given by:```Z = sqrt(R^2 + (XL - XC)^2)```where:* R is the resistance* XL is the inductive reactance* XC is the capacitive reactanceIf XC increases, then the term (XL - XC) decreases. This means that the impedance Z will increase. However, this is only true if XL is less than or equal to XC. If XL is greater than XC, then the term (XL - XC) will increase, and the impedance Z will decrease.
