Voltan (V) dalam litar elektrik diukur dengan menggunakan.....
Explanation
Voltan (V) dalam litar elektrik diukur dengan menggunakan voltmeter. A voltmeter is a device used to measure electrical potential difference or voltage. It is connected in parallel to the circuit component or across the two points where the voltage is to be measured. The voltmeter measures the potential difference between these two points and displays the voltage value on its scale. Therefore, a voltmeter is the correct instrument to measure voltage in an electric circuit.Rate this question:

Apakah kegunaan ammeter ?
- A.
Sukat rintangan elektrik
- B.
Sukat beban elektrik
- C.
Sukat jumlah arus elektrik
- D.
Sukat kuasa elektrik
Correct Answer
C. Sukat jumlah arus elektrikExplanation
An ammeter is used to measure the amount of electric current flowing through a circuit. It is specifically designed to measure the flow of current and is connected in series with the circuit. By measuring the current, an ammeter helps in determining the efficiency and performance of the circuit, as well as identifying any potential issues such as overloading or short circuits. Therefore, the correct answer is "Sukat jumlah arus elektrik" which translates to "Measure the amount of electric current".Rate this question:

Litar siri adalah litar yang menyambungkan lebih dari satu komponen elektrik tetapi hanya ada satu laluan sahaja untuk arus elektrik.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The given statement explains that a series circuit is a circuit that connects more than one electrical component but only has one valid path for electric current. This means that the components in a series circuit are connected one after another, forming a single pathway for the flow of electricity. Therefore, the statement is true.Rate this question:

Jenis sambungan litar ini menyambungkan antara komponen yang benarkan arus elektrik mengalir melalui lebih daripada satu laluan elektrik. Apakah nama sambungan litar ini ?
- A.
Litar selari
- B.
Litar siri-selari
- C.
Litar siri
- D.
Litar serentak
Correct Answer
A. Litar selariExplanation
The correct answer is "Litar selari". This type of circuit connects components in such a way that allows electric current to flow through more than one electrical path. In a parallel circuit, each component is connected to the same voltage source, but the current is divided among the different paths. This allows for independent operation of each component, as the failure of one component does not affect the operation of the others.Rate this question:

Hasil gabungan antara litar siri dengan litar selari dinamakan...
- A.
Litar kelompok
- B.
Litar sepadu
- C.
Litar gabungan
- D.
Litar siri-selari
Correct Answer
D. Litar siri-selariExplanation
The correct answer is "Litar siri-selari." This term refers to a combination of series and parallel circuits. In a series circuit, the components are connected in a single path, while in a parallel circuit, the components are connected in multiple paths. A series-parallel circuit combines both types of connections, allowing for a more complex electrical system. This type of circuit is commonly used in various applications, such as in household wiring or electronic devices, to provide a balance between voltage and current distribution.Rate this question:

Manakah antara berikut merupakan maksud istilah parameter elektrik yang telah disalah terjemahkan? (Pilih dua jawapan)
- A.
R = Radius
- B.
V = Voltan
- C.
I = Indeks
- D.
I = Arus
Correct Answer(s)
A. R = Radius
C. I = IndeksExplanation
The correct answer is R = Radius, I = Indeks. In this question, the term "parameter elektrik" refers to electrical parameters. The incorrect translation is the term "Indeks" which should be translated as "Index" instead. The correct translation for "Indeks" in the context of electrical parameters would be "Current" or "Arus" in Indonesian.Rate this question:

Apabila voltan (V) bertambah , arus elektrik akan berkurang.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When the voltage increases, according to Ohm's Law, the current will also increase, not decrease. This is because Ohm's Law states that the current is directly proportional to the voltage, meaning that as the voltage increases, the current will also increase. Therefore, the given statement is false.Rate this question:

Apabila rintangan bertambah, arus elektrik akan berkurang.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement suggests that when obstacles increase, the flow of electric current decreases. This is because obstacles create resistance in the circuit, hindering the flow of electrons. As a result, the current decreases as the resistance increases. Therefore, the given answer, "True," is correct.Rate this question:

Arus elektrik bernilai 0.5A dan rintangannya ialah 5 ohm. Berapakah jumlah voltannya? (petunjuk : V = I X R)
- A.
V = 2.0V
- B.
V = 2.5V
- C.
V = 2.2V
- D.
V = 3.0V
Correct Answer
B. V = 2.5VExplanation
The formula V = I x R is used to calculate the voltage. In this question, the current (I) is given as 0.5A and the resistance (R) is given as 5 ohms. Plugging these values into the formula, we get V = 0.5A x 5 ohms = 2.5V. Therefore, the correct answer is V = 2.5V.Rate this question:

Berikut adalah formula cara pengiraan parameter elektrik. Manakah formula pengiraan yang SALAH?
- A.
V = I X R
- B.
Kuasa = V X I
- C.
R = V / Kuasa
- D.
I = V / R
Correct Answer
C. R = V / KuasaExplanation
The given formula R = V / Kuasa is incorrect because the correct formula to calculate resistance (R) is R = V / I, where V is the voltage and I is the current.Rate this question:
