Advantages of using high voltage and low currentReduce transmission losses Resistance loss: According to Joule's law (P=I2R), the greater the current, the greater the resistance loss. Therefore, in the case of transmitting the same power, the use of high voltage and small current can significantly reduce the resistance loss. Wire size: The use of high voltage can reduce the current density in the wire, allowing the use of thinner wires and reducing material costs.Improve transmission efficiency

Thunderstorm generator definitionA thunderstorm generator is a device used to simulate lightning phenomena under thunderstorm weather conditions.Working principleA thunderstorm generator usually simulates the lightning discharge process by producing a high-voltage pulse. It can use the capacitor to discharge instantaneously after charging, or through other high-voltage discharge technology, to generate a strong electric field and current, so as to simulate the arc discharge and electromagnetic p

Historical development factorEarly power systems were dominated by alternating current: In the early days of power system development, alternator and transformer technology was relatively mature and easy to manufacture.Ac system can easily change the voltage level through the transformer to achieve high-voltage transmission to reduce line losses, so AC transmission has been widely used in the early days and formed a huge power grid system.Technical considerationsAdvantages of transformers in AC

Ensuring the safety of people passing under high-voltage wires is a crucial task. High-voltage transmission lines are designed and constructed according to strict safety standards and regulations to minimize risks to the public. Here are some common measures to ensure the safety of high-voltage wires:Using InsulatorsInsulators are commonly used components in high-voltage wires to fix the wires to towers or poles and prevent current from conducting through the towers or poles to the ground. Insul

Will the voltages of two different currents drawn from an AC source add up?The voltages of two different currents drawn from an AC (Alternating Current) source do not simply add up in the way that might be expected with direct current (DC) sources. To understand why, it's important to consider how voltage and current behave in AC circuits.Key Concepts in AC CircuitsImpedance (Z): In AC circuits, impedance is the measure of the total opposition that a circuit presents to a current due to the pres

What is the maximum current safe for the human body?The effect of electric current on the human bodyPerceptual threshold0.5 mA to 1 mA: This is the threshold at which most people can feel the current pass through. In this range, the body will feel a slight tingling or tingling sensation.Relaxation threshold5 mA to 10 mA: In this range, the current is sufficient to cause muscle contraction, making it difficult for the finger or hand to release the power voluntarily. This is called the "letting go
