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. Z=(V)/(I) If the voltage across a circuit element is 23+2i volts and the current through the element is 4-5i amperes, determine the impedance. The impedance is Z=square (Type your answer in the form a+bi

To determine the impedance
of the circuit element, we need to divide the phasor voltage
by the phasor current
. Given:
The impedance
is calculated as:
To simplify this expression, we multiply the numerator and the denominator by the complex conjugate of the denominator. The complex conjugate of
is
.So, we have:
First, calculate the denominator:
Next, calculate the numerator:
Now, divide the numerator by the denominator:
Therefore, the impedance
is:
