Kirchhoff's Voltage Law states that “The algebraic sum of all the voltages in a circuit loop is equal to zero”. Kirchhoff's Current law states “ Algebraic sum of all electric currents arriving at a junction (node) is equal to zero”. The reciprocal of the equivalent resistance for several resistances connected in parallel is equal to the sum of reciprocals of all resistances in the circuit. The equivalent resistance for several resistances connected in a series is equal to the sum of all individual resistances. Most commonly, it consists of a voltage source, and a load that consumes the voltage or across which a potential drop is observed. This equation depicts that the voltage gain inside a loop is equal to the voltage drop.Īn electric circuit consists of electrical components and provides a path for the current to flow. Here, the above equation can be written as Now, the algebraic sum of voltages in the above circuit will be Again, while passing through the resistance, a voltage drop will be experienced, which will be equal to iR. While passing through the voltage source (V), the current moves from negative to positive, which means voltage gain is observed at this point. The current flows in a clockwise direction in the circuit. The sum of voltages in the circuit is taken by taking a positive sign for voltage gain and a negative for voltage drop. Due to this current, a potential drop or rise is observed in the circuit. Let’s consider a closed loop of a circuit consisting of batteries and resistances assuming that the current flows in a clockwise direction in the loop. Kirchhoff's Voltage Law states that “ The algebraic sum of all the voltages or potential differences in a circuit loop is equal to zero”. This also shows that charges are conserved. It can be depicted from the above equation that the sum of currents arriving at a node is equal to the sum of currents leaving the node. In the above diagram, the algebraic sum of all currents is required to be zero. The equivalent resistance for several resistances connected in series is equal to the sum of all individual resistances. When Resistances are Connected in Series: The equivalent resistance can be determined using the following two methods. ![]() If there are two or more resistances present in the circuit, then it can be replaced with an equivalent resistance of the two resistances. The resistance or load is defined as the obstruction provided by several components of a circuit to the current flow. We shall be discussing all of these in detail in this article. The two laws of Kirchhoff are Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL). As the circuit gets complex, i.e., several loops are present, then Kirchhoff’s Laws are used. The most basic is Ohm’s law that is used to solve a simple circuit. Several laws have been formulated to help solve a circuit. Solving a basic electric circuit means to find the total resistance in the circuit, to determine the potential difference, or to find the current flowing in the circuit. When the circuit is closed, current flows through the circuit. A basic electric circuit could consist of a voltage source, and a load that consumes the voltage or across which a potential drop is observed. An electric circuit consists of electrical components and provides a path for the current to flow. ![]()
