3 buah lampu 5 watt 3,7 volt dipasang secara seri dan di aliri arus 12 volt, berapa nilai resistor yang harus dipakai?

Jawaban:

Fisika Listrik

Penjelasan:

R1 = R2 = R3 = R

R seri = R1 + R2 + R3 = R + R + R = 3R

[tex]P = \frac{V^{2} }{R} \\5 = \frac{3.7^{2} }{3R}\\ R = \frac{13.69}{15} \\R = 0.91[/tex]Ω
