Stumped On A Revision Question

[skystorm]

An A,c circuit has an Inductive reactance of 13ohms ,A capacitive reactance of 23ohms and Resistance of 18 ohms calculate the impedance of the circuit 

 is the formula 

XL =2 x 3.142 x 13 x 23=

(18 + 18.78) = 

Which formula to use

20.59 

 

[kerching]

NO

You need to treat it as 3 parts

Using. 1/2pi f C

2 pi f L

R

Looks disjointed as I cannot do symbols on iPad yet

Note to self...read he question and the given values......I over complicated it immensely, sorry

Sorry son is training with OLCI After been laid off can you show the formula please / or show working it out thanks 

 

[septiclecky]

How are the inductance, capacitance and resistance connected might help.

Thanks everyone (went blank, blond moment lol ) 18"+(23-13)"= 20.59
