# How To Solve Circuit Problems Kirchhoff's Voltage Law (KVL) states that the sum of all the potential drops in any closed loop of a circuit has to equal zero.More simply, KVL is a method of applying the law of conservation of energy to a circuit.

If 4 amps of current is flowing through the 3-ohm resistor, then 4 amps of current must be flowing through the 6-ohm resistor according to Kirchhoff's Current Law.In fact, most circuits actually have elements of both types.Analyzing these circuits can be accomplished using the fundamentals you learned in analyzing series and parallel circuits separately and applying them in a logical sequence.Determine the amplitude of electric current in the circuit and a phase difference between the voltage and the current. The table of contents will list only tasks having one of the required ranks in corresponding rankings and at least one of the required tags (overall).If you wish to filter only according to some rankings or tags, leave the other groups empty.To find the equivalent resistance of any number of series resistors, we just add up their individual resistances: Note that because there is only a single current path, the same current must flow through each of the resistors.A simple and straightforward method for analyzing circuits involves creating a VIRP table for each circuit you encounter.For example if our voltage was 4 Volts and our total resistance was 9 Ohm’s, then our current (I) would be 4/9 Amps, which is equal to 0.4444 Amps. The circuit is connected to an AC voltage source with amplitude 25 V and frequency 50 Hz.Kirchhoff's Current Law (KCL), named after German physicist Gustav Kirchhoff, states that the sum of all current entering any point in a circuit has to equal the sum of all current leaving any point in a circuit.More simply, this is another way of looking at the law of conservation of charge.
