Equivalent resistance, often abbreviated as r eq in electrical engineering, is a measure of whole combined resistance of 2 or more resistors connected in series or parallel. Equivalent resistance calculator free online calculator byjus. Resistance of a circuit is defined as the ratio of the voltage applied to the electric current which flows through it. The equivalent resistance of parallel resistors is computationally more complex. Equivalent resistance calculator free online calculator. Parallel resistance calculator daycounter engineering resources. Two resistors are connected to a battery in series. Download the file from this instructable called lrc instructable files. Know the value of the resistor r know how many resistors you are using n read the output x here is the. This tool calculates the overall resistance value for multiple resistances connected either in series or in parallel. Parallel resistor calculator is an online tool for electrical and electronic circuits to measure the equivalent resistance of the resistors connected in parallel.
In a circuit connected in series, the total resistance is found by simply adding up all the resistance values of the individual resistors, whereas in parallel it is found by adding up the reciprocals of the resistance values, and taking the reciprocal of the total. Physics 1 dc circuits series and parallel resistors. Calculating equivalent resistance for series and parallel resistors. Equivalent resistance calculator for android apk download. It converts both color to number and number to color. Byjus online equivalent resistance calculator tool makes the calculation faster, and it displays the equivalent resistance in a fraction of seconds.
The calculator does not go to 3 spots after the decimal and therefore, shows 0. Quickly calculate the resistance, inductance or capacitance of electronic components. When you do not have an exact resistor value in building a circuit, you need to combine two resistors either in series or in parallel. You can easily calculate the equivalent resistance when you. If the resistors have resistances of 4 ohms and 10 ohms, what is the equivalent resistance of the circuit. Switch to series and parallel capacitor calculator parallel resistor. Calculate the equivalent resistance r ab for each of the circuits in fig 2. To use it, just specify how many parallel resistors there are and the resistance value for each one. Parallel resistance calculator electronic products. The units will be consistant for all calcultion results will be in kohms for kohm input values.
