But while flowing through a wire of circuit it has to overcome the resistance given by the wire and flow through the circuit. The current is the discharge of electrons. The current opposes the flow of current which is said to be Resistance. Ohm’s law equations – As Ohm’s law states, the current is directly proportional to the voltage with resistance as the constant of proportionality. Therefore, the total amount of resistance applied by the circuit is given by 1/R equivalent = 1/R 1 + 1/R 2 + 1/R 3 + …… +1/R nĪlso Read : Ohm’s Law Pie Chart Explained The total equivalent current through the circuit is I equivalent= I 1+ I 2+I 3+ ….+ I n So by substituting, we get V/R_equivalent = V/R 1 + V/R 22+ V/R 3 + …. Then by Ohm’s law, the current through each resistor is given as: V Let the current flowing through the first resistor be ‘I 1’, through the second resistor be ‘I 2‘. The resistance of the first resistor be R 1, the second resistor be R 2and so on. Let us consider that the voltage across these resistors be ‘V’. The parallel combination of resistors is demonstrated below In the parallel connection, the voltage across one resistor is the same as the voltage across the different resistors connected in that circuit while the current flowing through each resistor varies according to each resistor. In a circuit, a connection of ‘N’ number of resistors can be done parallel to each other. Both the ends of a resistor are connected to both the ends of the other resistor. In a parallel circuit, the resistances can be joined parallel to each other i.e. Therefore, the total amount of resistance applied by the circuit is given by The total equivalent voltage across the circuit is V equivalent= V 11+ V 2+V 3+ ….+ V n Then by Ohm’s law, the voltage across each resistor is given as: V 1= I × R 1 Let the voltage across the first resistor be “, for the second resistor be ‘. The resistance of the first resistor is “, the second resistor is” and so on. Let us assume that ‘I’ is the current flowing through these resistors.

The series combination of resistors is shown below. In the series connection, the current flowing through all the resistors is the same, while the voltage across each resistor is different. ‘N’ number of resistors can be connected. Only one end of a resistor is connected to the end of the additional resistor. No other element of the circuit is connected between any two circuits. In a series circuit, the resistors are connected beside each other, i.e. The resistors can be joined in series or parallel or series and parallel both. There are two ways to a connection of resistors. Ohm’s Law for Combination of Resistors in Circuits

Also, it is referred to as Ohm when said about resistance. It is indicated by ‘’. This is a Greek uppercase letter called Omega. One ohm is the resistance produced by the flow of the current of one Ampere through a potential difference of one volt.
