Equivalent resistance is the total resistance of a combination of resistors in a circuit. It is a single resistance value that represents the combined effect of multiple resistors.
To calculate equivalent resistance, you can use Ohm's law (R = V/I) or the formula for parallel resistors (1/Req = 1/R1 + 1/R2 + ...). In series circuits, equivalent resistance is simply the sum of all the individual resistances.
Equivalent resistance is important because it helps simplify complex circuits by reducing multiple resistors into a single value. This makes it easier to analyze and understand the behavior of a circuit.
Yes, in series circuits, the equivalent resistance is always greater than the individual resistances. In parallel circuits, the equivalent resistance can be less than the individual resistances.
The arrangement of resistors (in series or parallel) will affect the value of the equivalent resistance. In series, the equivalent resistance is the sum of the individual resistances, while in parallel, the equivalent resistance is less than the smallest individual resistance.
