Question

Kak tolong bantu… dikasih keterangan “diketahui” sama “ditanya” ya kak

Answer 1

Verified answer

Pembahasan :

Diketahui :

• n = 10²⁰
• t =  4 Detik
• e = 1,6 x 10¹⁹ Coulomb
• R = 20 Ω

Ditanyakan :

• kuat arus yang melalui penghantar
• beda potensial ujung - ujung penghantar

Jawab :

1. Kuat arus

[tex]\displaystyle Q = I\times t\\\\I = \frac{Q}{t}\\\\I = \frac{n\times e}{t}\\\\I = \frac{10^{20}\times 1,6\times 10^{-19}}{4}\\\\I = \frac{1,6\times10}{4}\\\\I = 4 \text{ Amphere}[/tex]

2. Beda potensial

[tex]\displaystyle V = I\times R\\\\V = 4 \times 20\\\\V = 80 \text{ Volt}[/tex]
