Hambatan listrik adalah perbandingan antara tegangan dan ... listrik yang melewati komponen elektronik.
Correct Answer
E. Arus
Explanation
The correct answer is "arus". The question is asking for the comparison between voltage and a certain aspect of electric current that passes through electronic components. "Arus" is the term that represents the flow of electric charge, which is what passes through the components. The other options, such as "muatan" (charge), "resistansi" (resistance), "kapasitansi" (capacitance), and "induktansi" (inductance), are not directly related to the comparison between voltage and the flow of electric current.
2.
Arus listrik yang mengalir pada komponen elektronika dapat dihitung dengan menggunakan rumus ....
Correct Answer
A. I = V : R
Explanation
The correct formula to calculate electric current flowing through an electronic component is I = V : R. This formula represents Ohm's Law, where I is the current, V is the voltage, and R is the resistance. According to Ohm's Law, current is equal to the voltage divided by the resistance.
3.
Jika diketahui tegangan listrik, V
= 12 volt dan R = 12KOhm, maka arus listrik yang mengalir melalui
hambatan tersebut adalah sebesar ... A.
Correct Answer
A. 0,001
Explanation
The current flowing through a resistor can be calculated using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). In this case, the voltage is 12 volts and the resistance is 12KOhm (12,000 Ohm). Therefore, the current can be calculated as 12 volts divided by 12,000 Ohm, which equals 0.001 Ampere.
4.
Satuan yang digunakan untuk mendefinisikan besaran tegangan adalah ....
Correct Answer
A. Volt
Explanation
The correct answer is volt. Volt is the unit used to define the quantity of electric potential energy per unit charge in a circuit. It represents the amount of electrical force or pressure that is applied to move an electric charge through a conductor. Ampere is the unit for electric current, farad is the unit for capacitance, coloumb is the unit for electric charge, and newton is the unit for force.
5.
Jika diketahui sebuah resistor bernilai 2K2 akan memiliki cincin warna ....
Correct Answer
C. Merah-merah-merah
Explanation
The answer "merah-merah-merah" indicates that the resistor has three red bands. In the resistor color coding system, the first two bands represent the significant digits of the resistor value, and the third band represents the multiplier. Since all three bands are red, it means that the resistor has a value of 22 multiplied by 1, resulting in a total resistance of 22 ohms.
6.
Tegangan listrik adalah berbanding lurus dengan besarnya hambatan dan ... listrik yang melewati komponen elektronik.
Correct Answer
A. Arus
Explanation
The given statement states that the electric voltage is directly proportional to the resistance and the electric current that passes through an electronic component. The correct answer is "arus" which means current in English. This implies that the electric current is the determining factor in the relationship between electric voltage and resistance. As the electric current increases, the voltage across the component also increases, assuming the resistance remains constant.
7.
Jika diketahui tegangan listrik V
= 12 volt dan arus I = 0.12A, maka besarnya hambatan komponen
elektronik yang dilaluinya adalah sebesar ... ohm.
Correct Answer
D. 100
Explanation
The given question states that the voltage is 12 volts and the current is 0.12A. To find the resistance, we can use Ohm's law, which states that resistance is equal to voltage divided by current. Therefore, the resistance can be calculated as 12V/0.12A = 100 ohms.
8.
Komponen elektronika yang digunakan untuk membagi tegangan dalam rangkaian elektronika adalah ....
Correct Answer
B. Resistor
Explanation
Resistors are electronic components that are used to divide voltage in an electronic circuit. They provide resistance to the flow of electric current, which in turn helps in reducing the voltage across a specific part of the circuit. By controlling the resistance value, resistors can effectively divide the voltage and regulate the flow of current.
9.
Satuan yang digunakan untuk mendefinisikan besaran resistansi adalah ....
Correct Answer
C. Ohm
Explanation
The correct answer is ohm. Ohm is the unit used to define the electrical resistance of a material or component. It is named after the German physicist Georg Simon Ohm and is represented by the symbol Ω. The resistance of a material determines how much it opposes the flow of electric current. The higher the resistance, the lower the current flow. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its resistance.
10.
Jika diketahui sebuah resistor memiliki cincin warna: KUNING-UNGU-ORANGE akan memiliki nilai sebesar ... ohm.
Correct Answer
B. 47 K
Explanation
The resistor with the color code KUNING-UNGU-ORANGE indicates a value of 47 K ohm. The first band, KUNING (yellow), represents the number 4. The second band, UNGU (purple), represents the number 7. The third band, ORANGE, represents the multiplier 1,000. Therefore, the resistor's value is calculated as 47 x 1,000 = 47,000 ohms, which is equivalent to 47 K ohm.
11.
Jika diketahui sebuah resistor bernilai 330 Ohm, memiliki cincin warna ....
Correct Answer
B. Orange-orange-coklat
Explanation
The correct answer is orange-orange-coklat. The color code for resistors is used to determine their resistance value. In this case, the first two bands are orange, which represents a value of 3, and the third band is brown, which represents a multiplier of 10. Therefore, the resistance value of the resistor is 33 x 10 = 330 Ohm.
