What Is Equivalent Resistance In A Circuit
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated.
What is equivalent resistance in a circuit. In a series circuit the total resistance is equal to the sum of all resistances. In a given combination of resistors series parallel or combination of series parallel the equivalent resistance is that value of resistance which when replaced in place of the combination will continue to give the same performance for the. Equivalent resistance of a circuit is obtained by calculating parallel and series elements in a circuit. For example a series circuit has a 2 ω ohm resistor a 5 ω resistor and a 7 ω resistor.
This physics video tutorial provides a basic introduction into equivalent resistance. Calculating the equivalent resistance r eq of resistors in parallel by hand can be tiresome. Electrical resistance shows how much energy one needs when you move the charges current through your devices. Equivalent resistance is a different way of indicating total resistance which we calculate differently for series and parallel circuits.
The equivalent resistance for orange and red. The total resistance of the circuit is 2 5 7 14 ω. Essentially the circuit is designed either in series or parallel. To use it just specify how many parallel resistors there are and the resistance value for each one.
It explains how to calculate the equivalent resistance of complex circu. In electric circuits equivalent resistance depends on the arrangement of the resistors and the location of the voltage source. In this topic on how to calculate equivalent resistance we have to simplify the circuit elements. View attachment 258269 as davee pointed out earlier the orange and red resistors are not in parallel due to the yellow resistor between them.
If you re seeing this message it means we re having trouble loading external resources on our website. Practice finding the equivalent resistance for parallel and series resistor configurations. Similar upscaling techniques motivated by the need to reduce grid block number are important in practice. The same current passes through each resistor so each resistor does its job as you would expect.
This tool was designed to help you quickly calculate equivalent resistance whether you have two or ten resistors in parallel.
