Arah arus listrik yang tepat dapat dinyatakan sebagai berikut &hellip;.

Memperbesar tegangannya menjadi 4 kali semula.

Memperkecil tegangan menjadi 2 kali semula.

Memperbesar hambatan menjadi 2 kali semula.

Memperkecil hambatan menjadi 0,25 kali semula.

Memperkecil hambatan menjadi 0,5 kali semula.

Rogu menginginkan kuat arus listrik yang mengalir pada alat percobaannya sebesar 2 kali semula, maka hal yang dapat dilakukan adalah &hellip;

Pada suatu rangkaian listrik dengan hambatan yang bernilai tetap diperoleh grafik hubungan tegangan (V) dengan kuat arus (I) seperti gambar berikut.

&nbsp;<img alt="" src="https://imgix2.ruangguru.com/assets/miscellaneous/jpg_otbid7_3335.JPG" style="width: 153px; height: 135px;" />&nbsp;

Jika <m:r>V&nbsp;</m:r><m:r>= 4,5 </m:r><m:r><m:rpr><m:scr m:val="roman"><m:sty m:val="p"></m:sty></m:scr></m:rpr>V,</m:r>&nbsp;kuat arus yang mengalir adalah &hellip; .

Setiap kawat atau penghantar memiliki sifat menghambat arus listrik, besaran &ndash; besaran berikut mempengaruhi hambatan setiap penghantar, yaitu:

<ol>
	<li>Massa kawat</li>
	<li>Panjang kawat</li>
	<li>Warna kawat</li>
	<li>Luas penampang kawat</li>
</ol>

Pernyataan yang benar ialah &hellip;.

Panjang kawat penghantar 1 &gt; panjang kawat penghantar 3 &gt; panjang kawat penghantar 2

Panjang kawat penghantar 1 &lt; panjang kawat penghantar 3 &lt; panjang kawat penghantar 2

Luas penampang kawat penghantar 1 &gt; luas penampang kawat penghantar 3 &gt; luas penampang kawat penghantar 2

Luas penampang kawat penghantar 1 &lt; luas penampang kawat penghantar 2 &lt; luas penampang kawat penghantar 3

Hal ini tidak dapat ditentukan karena tidak diketahui nilai koefisian hambatan jenis kawat penghantar

Terdapat 3 jenis kawat penghantar dengan koefisien hambatan jenis kawat yang sama. Jika diketahui hambatan kawat penghantar 1 &gt; hambatan kawat penghantar 3 &gt; hambatan kawat penghantar 2, maka pernyataan yang tepat adalah &hellip;.

Rogu sedang melakukan praktikum yang bertujuan untuk mengamati jumlah muatan yang mengalir pada suatu rangkaian tertutup. Hasil pengukuran pada amperemeter yang digunakan Rogu menunjukkan angka 5 A selama 2 menit, maka jumlah muatan yang mengalir pada rangkaian tersebut sebesar &hellip;.

Sebuah bola lampu yang filamennya terbuat dari tungsten memiliki hambatan listrik 20 ohm ketika suhunya 80 &deg;C. Hambatan bola lampu ini pada suhu 120 &deg;C adalah &hellip; (koefisien hambatan jenis untuk tungsten adalah 0,0045 /&deg;C).

Sebuah kawat konduktor dengan hambatan jenis 1,6 &times; 10-8 &Omega;m memiliki panjang 157 cm dan jari-jari penampang 2 cm dihubungkan dengan sumber tegangan 0,001 V. Kuat arus yang mengalir pada kawat konduktor tersebut adalah &hellip;.

Dua buah kawat konduktor, A dan B, yang berbeda jenis mula-mula memiliki temperatur yang sama. Hambatan awal kawat A dua kali hambatan awal kawat B. Setelah dipanaskan, kawat A mengalami perubahan suhu setengah kali perubahan suhu kawat B.

Sebuah sumber tegangan dihubungkan dengan seutas kawat konduktor yang memiliki jari-jari penampang sebesar r sehingga pada kawat tersebut mengalir arus sebesar I.
