Electricity resembles the flow of water. The potential difference between two places can be expressed as a voltage. Voltage is the “pressure,” as it were, that makes electricity flow. In physics, voltage can be calculated using Ohm’s Law, which tells us that voltage equals resistance times...
This law is devised by dr.ohm in 1827 it is fundamental law in electricity. It relates to the potential difference (V), current (I), resistance(R), of the
What is Ohm's law? Why is it a law and not a theory?Ohm's LawIf through a resistance circulates an electric current between the extremes of the resistance appears a potential difference, The relationship that is established between these three magnitudes is linear and is given by Ohm's ...
Key learnings: Electric Current Definition: Electric current is defined as the flow of charged particles—such as electrons or ions—through a conductor or space. Electric Current Formula: The flow rate of electric charge is calculated by dividing the change in charge by the change in time. ...
rArr Current density : The electric current density at any point is defined as amount of electric current flowing per unit cross section perpendicular to the current at that point. Current density is Vector quantity, vec(J) = (I)/(vec(A)) Unit = (
