straight R space equals space 12 space ohm space semicolon space straight L space equals space 0 comma 075 space straight H space semicolon space straight C space equals space 500 space μF  straight omega space equals space 200 space rad divided by straight s  straight I subscript maks space ?

straight V space equals space straight V subscript straight m space sin space ωt  straight V space equals space 26 space sin space 200 straight t

Maka space diketahui colon

straight V subscript maks space equals space straight V subscript straight m space equals space 26 space straight V  straight omega space equals space 200 space rad divided by straight s

Hitung space terlebih space dahulu space reaktansi space kapasitif space dan space space reaktansi space induktif space pada space rangkaian space RLC

straight X subscript straight C space equals space 1 over ωC space equals space fraction numerator 1 over denominator left parenthesis 200 right parenthesis left parenthesis 500 cross times 10 to the power of negative 6 end exponent right parenthesis end fraction space equals space 10 space ohm  straight X subscript straight L space end subscript equals space ωL space equals left parenthesis 200 right parenthesis left parenthesis 0 comma 075 right parenthesis space equals space 15 space ohm

Hitung space impedansi space rangkaian colon

straight Z space equals space square root of straight R squared plus left parenthesis straight X subscript straight L minus straight X subscript straight C right parenthesis squared end root  straight Z space equals space square root of left parenthesis 12 right parenthesis squared plus left parenthesis 15 minus 10 right parenthesis squared end root  straight Z space equals space square root of 144 plus 25 end root space equals space square root of 169  straight Z space equals space 13 space ohm

Besarnya space kuat space arus space listrik space maksimum space yang space mengalir space pada space rangkaian space RLC space space adalah colon

straight I subscript maks space end subscript equals space straight V subscript maks over straight Z  straight I space equals space 26 over 13 space equals space 2 space straight A
