The impedance Z, in ohms, of a circuit element is defined as the ratio of the phasor voltage V, in volts, across the element to the phasor current I, in amperes, through the elements. That is, Upper Z equals StartFraction Upper V Over Upper I EndFraction . If the voltage across a circuit element is 23 plus 14 i volts and the current through the element is 5 minus 2 i amperes, determine the impedance.
