1. The problem statement, all variables and given/known data

Please check the attachment to see all the variables

2. Relevant equations

Xl=2*pi*f*l, Xc=1/2*pi*f*c, variation of ohms law

3. The attempt at a solution

Ok for 5) i found Xl & Xc, then i combined the resistances in parrallel and used ohms law to find I=v/r. My answer was I=19

For 6) Im complete confused by the circuit, it dosnt make sence to me

For 7) parallel resistor?

Question 6 is a bit ambiguous. The total reactance of the circuit is made up of a capacitive part and an inductive part. The result Xl - Xc is usually referred to as 'the reactance' qualified by the word 'capacitive' of 'inductive' depending on which is the larger.

Anyway in this case - I think it just means the reactance of the capacitor - which you've already calculated.

Figure 12-2 makes no sense at all. There are 2 capacitors but 3 values given
If we assume that one is missing from the drawing, it's probably the 10uF and it could be in parallel with the others, or in series.
Only one configuration would give a value that's offered as an answer.
