10 Interesting facts about voltage and Current

10 Interesting facts about current

1. Electric current is the flow of electric charge through a conductor, such as a wire.
2. The standard unit of electric current is the ampere (A), named after French scientist André-Marie Ampère.
3. Direct current (DC) flows in one direction, while alternating current (AC) changes direction periodically.
4. Thomas Edison was a proponent of direct current (DC) for electric power distribution, while Nikola Tesla and George Westinghouse supported alternating current (AC).
5. AC is more efficient for long-distance transmission of electric power, which is why it is more widely used in the power grid today.
6. The human body can conduct electricity and can be affected by electric current. A current of as little as 0.1 A can cause muscle contractions and a current of 100 mA can cause cardiac arrest.
7. Superconductivity is a phenomenon where a material has zero electrical resistance and can conduct electricity with 100% efficiency at extremely low temperatures.
8. The phenomenon of electromagnetic induction was discovered by Michael Faraday in 1831, which led to the development of the electric generator.
9. Electric currents can create magnetic fields and vice versa, this phenomenon is known as electromagnetic field theory.
10. Electric current can cause electrolysis, the process of breaking down a chemical compound using an electric current.

10 interesting facts about voltage

1. Voltage, also known as electric potential difference, is the measure of electric potential energy per unit charge.
2. The standard unit of voltage is the volt (V), named after Italian physicist Alessandro Volta.
3. Voltage is the force that pushes electric charge through a circuit, similar to how water pressure pushes water through a pipe.
4. Voltage is the primary factor that determines the amount of current flowing through a circuit.
5. Voltage is measured between two points in an electric circuit, typically between a power source and a load.
6. The voltage across a circuit component is called the electric potential difference.
7. In a direct current (DC) circuit, voltage is constant, while in an alternating current (AC) circuit, voltage changes over time.
8. Voltage drop is the decrease in voltage along a circuit caused by resistance, it can cause a reduction in the amount of current flowing through the circuit.
9. High voltage can cause an electrical breakdown, where an electric current exceeds the capacity of a material, resulting in arcing or sparks.
10. In a circuit, Voltage and current are related by Ohm’s law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points.
