How do I figure out the impedance if the figures are shown in watts? I am used to seeing the values in rectangular form.

Picture looks ok to me pal, you can see the power figures in place instead of the usual Z impedance. I was saying I have never came across this before.
Impedance is a measure of the opposition to an alternating current (AC) in a circuit. It is important in science because it helps us understand the behavior and characteristics of electrical circuits, which are essential in many scientific fields such as physics and engineering.
Resistance is a measure of the opposition to current flow in a direct current (DC) circuit, while impedance takes into account the effects of both resistance and reactance (the opposition to changes in current due to capacitance or inductance). In other words, impedance is a more comprehensive measure of the opposition to current flow in an AC circuit.
Yes, impedance can be negative in certain cases where the effects of capacitance and inductance cancel each other out. This is known as a purely resistive circuit, where the impedance is purely real and can be either positive or negative.
Impedance is calculated using the formula Z = R + jX, where Z is the impedance, R is the resistance, and jX is the reactance. The reactance is calculated as either X = 1/ωC (for capacitance) or X = ωL (for inductance), where ω is the angular frequency and C and L are the capacitance and inductance values, respectively.
Impedance can have a significant impact on the performance of electronic devices, as it determines the amount of current that can flow through a circuit. If the impedance is too high, it can lead to voltage drops and signal loss, while a low impedance can cause excessive current flow and damage to the circuit. Therefore, it is important to carefully consider impedance when designing and using electronic devices.
