- C.
Energi 440 J/menit dan arus listrik 0,5 A
- D.
Energi 440 J/ menit dan arus listrik 2 A
- E.
Energi 440 J/jam dan arus listrik 2 A
Correct Answer
B. Energi 440 J/s dan arus listrik 2 AExplanation
The given information states that the electric iron is labeled as 440W/220V. This means that the power consumption of the iron is 440 Watts and the voltage required is 220 Volts. The formula for power is P = VI, where P is power, V is voltage, and I is current. By rearranging the formula, we can solve for I: I = P/V. Substituting the given values, we get I = 440W/220V = 2A. Therefore, the correct answer is "Energi 440 J/s dan arus listrik 2 A", which means the iron requires a power of 440 J/s and a current of 2 A.Rate this question:

- B.
Nilai kapasitor lebih tinggi
- C.
Tegangan input naik
- D.
Tegangan input kurang sekali
- E.
Kumparan motor terbakar
Correct Answer
D. Tegangan input kurang sekaliExplanation
Ketika tegangan input motor kurang sekali, kapasitor tidak akan mampu memberikan tegangan yang cukup untuk menjaga kumparan stator agar tetap berfungsi dengan baik. Akibatnya, kumparan stator dapat mengalami overheating atau terbakar karena tidak mendapatkan daya yang cukup. Hal ini menjadikan tegangan input yang kurang sekali sebagai salah satu gangguan pada motor kapasitor yang dapat menyebabkan kumparan stator terbakar.Rate this question:

Bengkel listrik luasnya 224 m2, menggunakan system penerangan langsung dengan η=0,5, jumlah titik penerangan 14 masing- masing 2x3200 lumen. Kuat penerangan yang dihsilkan adalah…
- A.
150 lux
- B.
200 lux
- C.
250 lux
- D.
300 lux
- E.
350 lux
Correct Answer
B. 200 luxExplanation
The question provides information about a workshop with an area of 224 m2. It mentions that the workshop uses a direct lighting system with an efficiency (η) of 0.5. It also states that there are 14 lighting points, each producing 2x3200 lumens. The question asks for the resulting illumination level.
To calculate the illumination level, we need to find the total luminous flux and divide it by the area of the workshop. The total luminous flux can be calculated by multiplying the number of lighting points by the luminous flux of each point. In this case, it would be 14 x (2 x 3200) lumens.
Next, we divide the total luminous flux by the area of the workshop and multiply it by the efficiency (η) to get the resulting illumination level.
Therefore, the correct answer is 200 lux.Rate this question:

- C.
1,95 Kgm
- D.
2,51 Kgm
- E.
1,25 Kgm
Correct Answer
E. 1,25 KgmExplanation
The correct answer is 1,25 Kgm. The moment of rotation (momen putaran) of an electric motor can be calculated using the formula: moment of rotation = power (daya) / angular velocity (putaran). In this case, the power is given as 3 KW (3000 W) and the angular velocity is given as 1500 rpm. Converting the angular velocity to rad/s (1500 rpm = 1500/60 = 25 rad/s), we can calculate the moment of rotation as 3000/25 = 120 Kgm. Therefore, the correct answer is 1,25 Kgm.Rate this question:

Correct Answer
B. 200 lilitanExplanation
The number of turns in the secondary coil of a step-down transformer can be determined using the formula:
(Ns/Np) = (Vs/Vp)
Where Ns is the number of turns in the secondary coil, Np is the number of turns in the primary coil, Vs is the voltage of the secondary coil, and Vp is the voltage of the primary coil.
In this case, the voltage ratio is (220/2200) = 1/10.
Since the primary coil has 2000 turns, the number of turns in the secondary coil can be calculated as:
Ns = Np x (Vs/Vp) = 2000 x (1/10) = 200 turns.
Therefore, the correct answer is 200 turns.Rate this question:

- D.
25 A
- E.
30 A
Correct Answer
B. 15 AExplanation
The power output of the transformer is given as 30 KW, and the input voltage is given as 2000 volts. To find the current through the primary coil, we can use the formula: power = voltage x current. Rearranging the formula to solve for current, we have: current = power / voltage. Substituting the given values, we get: current = 30,000 / 2000 = 15 A. Therefore, the correct answer is 15 A.Rate this question:
