- Chapter 12: Fundamentals of Electricity & Electronics › Current
Current Electrons in motion make up an electric current. This electric current is usually referred to as “current” or “current flow,” no matter how many electrons are moving. Current is a measurement of a rate at which a charge flows ... electrons. The greater amount of charge moving through the conductor in a given amount of time translates into a current. Current = Charge Time or I = Q t Where: I = current in amperes (A) Q = charge in coulombs (C) T = time…

total current flow into the node A equals the sum of the branch currents, which is: IT = I1 + I2 Substitute IT = 5 mA + 12 mA IT = 17 mA The total current entering node B is also the same. Figure ... illustrates how to determine an unknown current in one branch. Note that the total current into a junction of the three branches is known. Two of the branch currents are known. By rearranging the general formula, the current in branch…

Current Source A current source is an energy source that provides a constant value of current to a load even when the load changes in resistive value. The general rule to remember is that the total current produced by current ... sources in parallel is equal to the algebraic sum of the individual sources. Kirchhoff’s Current Law Kirchhoff’s Current Law can be stated as: the sum of the currents into a junction or node is equal…
