Equivalent resistance is the combined resistance of multiple resistors in a circuit. It is a single value that represents the total resistance in a circuit that can replace the original resistors without changing the overall behavior of the circuit.
To calculate equivalent resistance in a series circuit, you simply add the resistance values of each resistor. In a parallel circuit, you use the equation 1/Req = 1/R1 + 1/R2 + 1/R3 + ..., where Req is the equivalent resistance and R1, R2, R3, etc. are the resistance values of each individual resistor.
In a series circuit, the resistors are connected one after the other in a single path, whereas in a parallel circuit, the resistors are connected in branches. In a series circuit, the current remains constant throughout, while in a parallel circuit, the current is divided among the branches.
Equivalent resistance simplifies complex circuits and makes it easier to analyze the behavior of a circuit. It allows us to replace multiple resistors with a single value, making calculations simpler. It also helps in determining the power dissipated in a circuit and the overall efficiency of the circuit.
Yes, equivalent resistance can be greater than the largest individual resistor in a parallel circuit. This is because in a parallel circuit, the total resistance is less than the smallest resistor. However, in a series circuit, the equivalent resistance will always be greater than any individual resistor in the circuit.
