part A and D and E and F

Expert Solution
Step 1

In phasor notation, the input ac voltage can be expressed as

Electrical Engineering homework question answer, step 1, image 1

The frequency of the input ac source is given as

Electrical Engineering homework question answer, step 1, image 2

So, the angular frequency will become

Electrical Engineering homework question answer, step 1, image 3

 

 

Step 2

d)

Since it a series RLC circuit, the total impedance of the circuit will be

Electrical Engineering homework question answer, step 2, image 1

The magnitude and the phase angle of the impedance will be

Electrical Engineering homework question answer, step 2, image 2

So, in phasor notation, the impedance will be

Electrical Engineering homework question answer, step 2, image 3

Step 3

e)

The supply current I can be obtained by dividing the supply voltage with the total impedance of the circuit. 

Plugging the values, the value of the supply current becomes
