8. 1 Write a complex number to represent the impedance of each element. The voltage, V, is the real part, and the current, I, is the multiple of the imaginary unit i. 9. V = 34 volts: I = 3 milliamperes

10. V = 13 volts; I = 2.4 milliamperes

Given that,

Voltage = 34 volt

Current = 3i mA

We need to calculate the complex number to represent the impedance

Using ohm's law

Where, V = voltage

I = current

R = impedance

Put the value into the formula

(b). Given that,

Voltage = 13 volts

Current = 2.4 mA

We need to calculate the complex number to represent the impedance

Using ohm's law

Put the value into the formula

Hence, (a). The complex number to represent the impedance is

(b). (a). The complex number to represent the impedance is

i am sure it will be 90 degrees.
