Users questions: What is voltage what is meant
Experts answer: Hello! Current is produced? We know that water flow in the tube, we call it water. Similarly, the electronic movement of the wire can be, this flow of electrons is called current. Current general use of symbols "I" said. Water flow in a hierarchy, There are also in the flow of electric strength of the other. Current laugh with current intensities. Current strength is numerically equal to one second cross-section of electricity through the wire size. Commonly referred to as the current size, refers to the size of current intensity. General said that the current strength of the unit is the ampere, called security, with the symbol "A" Said. Stream in some circuits the current is very small, usually mA microamps measured. Conversion between them is: 1 Amp = 1000 milliamperes (mA) 1 = 1000 microamps ( A) voltage is produced? Can use "pressure" to imagine the production. Highly different stressful Different, resulting in potential energy, resulting in water flow. Voltage is the same, because the potential difference existing between two points, resulting in the positive potential of charged ions from high to low potential flow, creating current. It is noteworthy that negatively charged electron, but the flow from the low potential of high potential. It defines the positively charged particles as "power The direction of flow. "Not the same as in series and parallel! To light bulbs in series and parallel example: the case of parallel, either side of the parallel voltage equal to a line is broken light bulb does not affect the other lines work; series of case the current flowing through each bulb is equal, but each bulb voltage, whereas And a light bulb is broken, it will affect the work of other bulbs.
