Example 1: Consider two resistors 20Ω and 40Ω are connected in a parallel with a current source of 20 A. For your practice use the value of total current, resistance R1 and R2 to find the currents I1 and I2. Given data: R1 = 20Ω, R2 = 30Ω, R3 = 40Ω and V = 100 V. Now, add equation (13), (14) and (15) we get. In general, the current in any branch is equal to the ratio of opposite branch resistance to the total resistance value, multiplied by the total current in the circuit. A general formula for the current IX in a resistor RX that is in parallel with a combination of other resistors of total resistance RT is (see Figure 1): where IT is the total current entering the combined network of RX in parallel with RT. In other words, in a parallel circuit, the supply current splits into a number of parallel paths. Put this value of I1 into equation (1) we get, Now put this equation of I2 into equation (2), we get. These cookies do not store any personal information. The circuit divider rule explains the way in which the current at any node divides among the different branches. = Total Current flowing through the current divider or the array of resistors. Given data: R1 = 20Ω, R2 = 40Ω and IT = 20 A. Using the parallel resistance formula solve 5 and 10 ohms. There is however a small mistake in equation 7. When an amplifier is terminated by a finite, non-zero termination, and/or driven by a non-ideal source, the effective gain is reduced due to the loading effect at the output and/or the input, which can be understood in terms of current division. Suppose we want to know the current through R 2. The input source is 800 mA. The easy method which should be followed here is to find the equivalent resistance first, and then to apply the original formula: Derivation of Current Divider formula. …. Current divider rule can be applied only to parallel circuits in which the current is divided. Instead of using impedances, the current divider rule can be applied just like the voltage divider rule if admittance (the inverse of impedance) is used. However, the ratio describing current division places the impedance of the considered branches in the denominator, unlike voltage division where the considered impedance is in the numerator. Current division refers to the splitting of current between the branches of the divider. etc., then the reciprocal of each resistor must be added to find the total resistance RT: Although the resistive divider is most common, the current divider may be made of frequency dependent impedances. The proportionality between different branch currents is strictly a function of resistance. Such components can be solved by using the formula: For example, previously we solved 2-ohm resistor in parallel to 10-ohm resistor. 240 Ω ) = 0.5 A: This value of 0.5 amps per light bulb correlates with the value obtained from Joule’s Law directly for each lamp: 0.5 amps from the given values of … In this post you’ll learn: The electrical current flowing across the parallel resistors in inversely proportional to the magnitude of their resistances. To be specific, if two or more impedances are in parallel, the current that enters the combination will be split between them in inverse proportion to their impedances (according to Ohm's law).
