Current electricity is defined as the flow of electrons from one section of the circuit to another. Electromotive Force (EMF) and Voltage: When two bodies at different potentials are linked with a wire, free electrons stream from Point 1 to Point 2, until both the objects reach the same pot...
Where, Electric current is the rate of change of electric charge through a circuit. This electric current is related to the voltage and resistance of the circuit. Using Ohm’s law, we can represent as the formula: I=VR Where, Since we measure the charge in coulombs and time in seconds,...
Electric current is defined as flow of electrons in wire. Formula for current is I=Q/t, where Q is charge & t is time. Unit of electric current is ampere.
A formula known as Richardson’s law (first proposed by the English physicist Owen W. Richardson) is roughly valid for all metals. It is usually expressed in terms of the emission current density (J) as in amperes per square metre. The Boltzmann constant k has the value 8.62 × 10−5...
Combining the elements of voltage, current, and resistance, Ohm developed the formula:WhereV = Voltage in volts I = Current in amps R = Resistance in ohmsThis is called Ohm's law. Let's say, for example, that we have a circuit with the potential of 1 volt, a current of 1 amp, ...
