Deskripsi Program
Program ini dibuat agar memudahkan penggunanya dalam penghitungan
hambatan (resistor), tegangan (voltase), dan arus (current). Dalam permulaan
program ini pengguna akan dihadapkan pada 2 pilihan yaitu, rangkaian seri atau
rangkaian paralel, tergantung dari kebutuhan pengguna maka program akan
berjalan sesuai pilihan tersebut. Pada penghitungan hambatan, didesain hanya
untuk 3 masukkan (input) saja untuk menghasilkan keluaran (output) berupa
hambatan pengganti (Rs atau Rp). Terdapat perbedaan dalam pemrograman antara
rangkaian seri dan paralel, khususnya pada penghitungan hambatannya karena berdasarkan
hukum kirchoff yang berlaku, namun dalam penghitugan arus maupun tegangan
menggunakan formula yang sama. Maka untuk input yang sama hasil yang didapat
pada rangkaian seri dan rangkaian paralel adalah berbeda.
Langkah Pembuatan
1. Buat form seperti di bawah ini :
Ubah properties dari komponen tersebut seperti ini
Lalu
masukkan kode berikut :
Public Class Form2
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide()
Form3.Show()
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Hide()
form4.Show()
End Sub
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CenterToScreen()
End Sub
End Class
2. Buat form seperti di bawah ini :
Ubah properties dari komponen tersebut seperti ini :

Memang sangat panjang programnya tapi itu saya buat untuk memberikan kemudahan bagi penggunanya agar ketika digunakan sang pengguna merasa seperti sedang menjalankan program berbayar yang komersil, karena dalam program ini saya masukkan beberapa kecanggihan kecil. Jadi monggo buat yang pengen mencoba, saya jamin akan rasa puas anda akan terpenuhi, minimal akan geleng-geleng kepala saking banyaknya kodenya. Haha
Kalo masih belum jelas bisa download programnya di sini
