Physics voltage equation
WebbIt is named after the Italian physicist Alessandro Volta (1745–1827). Definition [ edit] The potential difference between two points is said to be 1 volt if 1 joule of work is done in moving 1 coulomb of electric charge from one point to the another. •It is denoted by 'V' •The device to measure potential difference is voltmeter WebbVoltage is measured in volts. The symbol for volts is \ (V\). For example, \ (230V\) is a bigger voltage than \ (12V\). Measuring voltage Voltage is measured using a voltmeter. …

WebbIn physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. [1] [2] [3] Power is a scalar quantity. WebbVolt can be stated in SI base units as 1 V = 1 kg m 2 s -3 A -1 (one-kilogram meter squared per second cubed per ampere). V = A.
