pozitif yarı-döngü akım akışlar dan canlı tel to nötr tel, ve negatif yarı-döngü akışlar dan sıfır tel to canlı tel. neden yapar canlı tel her zaman ışık yukarı ne zaman kullanan an elektrik test kalem?
Use the electric test pen to measure the live wire is bright because the voltage of the live wire to the ground is 220V. When measuring, the live wire passes through the resistance in the electric pen and grounds through the human body. At this time, there will be current flowing, so the light will be on. The neutral line has a voltage of zero volts to the ground, because the neutral line itself is connected to the ground and is at the same potential as the ground where you are, so there is no potential difference and no current can be formed, so naturally it will not light up.
The reason why the neutral line is zero is çünkü o is grounded, and the specified potential of the earth is zero, so the natural potential of the neutral line is zero. This is also the reason why the human body will not get an electric shock when standing on the ground and grabbing the neutral wire.
The neutral line is the line drawn the neutral point of the transformer. It is the return line from the live wire to the electrical appliance. The ground wire in is the protective earth where your home is location. Çünkü the earth also has resistance, sometimes the neutral line in the home will also be charged, but the voltage is very small and will not cause personal danger.
The potansiyel of the live line in the positive half cycle is high than the zero line, and the potential of the live line in the negatif half cycle is lower than the zero line. The water flows to the lower place, and the current is the same. Here need to correct a misunderstanding. Many people think that the current can only flow from the positive pole to the negative pole. In fact, the current also flows from the positive pole to the negatif pole. pozitif pole with high potential flows to positive pole with low potential
The potansiyel bahsedilen burada olabilir değil ol anlaşılan tarafından kişi kim sorulan bu soru, ve o can ayrıca be anlaşıldı as voltage. In fact, it is not the same concept. Voltage is a potential difference. Orada iki rezervuarlar, bir is 100 metre (potansiyel) ve the other is 150 metre (potansiyel), then onların yükseklik fark (voltaj) is 50 metre. If the two reservoirs are connected, the high water will akış to the low one. If both are 150 metre (potansiyel) ) would be impossible to flow (sıfır voltaj), even if onların yüksekliği (potansiyel) is high
Eğer siz anlamak yukarıdaki 2c potansiyel of the zero line is farumed to be the surface of the well, and the height is fixed. The live line is a bucket filled with water, and the height is variable. When the bucket is above the surface of the well, the water will flow to the surface of the well, otherwise the water on the surface of the well flow to kova
Neden yapar test kalem ışık yukarı on canlı çizgi ve değil on nötr çizgi? O öyledir çünkü üst test test kalem ihtiyaçlar to be bağlı insan bedeni ve sonra bağlı dünyaya 2c ve nötr çizgi is ayrıca bağlı dünyaya dünyaya bağlı onlar aynı potansiyele sahiptirler
