What Is Current Division Formula

21 May, 2021

A parallel circuit has the same voltage across all components but current always divide into parallel components. The formula for current division rule may be written as below.

Voltage across the parallel circuit as the voltage is same across all the components of the parallel circuit In terms of impedance the formula for a current divider is given by.

What is current division formula. Clicktap the circuit above to analyze on-line or click this link to Save under Windows. Current Divider Formula. This rule is very important and widely used in the field of electric engineering in different applications.

Statement and formula of Current Divider. R 2 Resistance across which current is to be determined 4 Ω. According to the current division rule the current through any branch is equal to the ratio of the total resistance in parallel to the branch to the total resistance multiplied by the total current in the circuit.

Ix RtRx It. In terms of admittance the formula for a current divider is given by. I 1 IxR 2 R 1 R 2 I 2 IxR 1 R 1 R 2 Carefully observe the above formula.

The current source iSt 5 cos wt A the resistor R 250 mohm the inductor L 53 uH and the frequency f 1 kHz. Putting the value of V I 1 R 1 from the equation 5 in equation 4 we finally get the equation as. Applying current division rule in the above circuit Current flow through R1 I 1 I T.

And now considering V I 2 R 2 the equation will be. Thus in the current division rule it is said that the current in any of the parallel branches is equal to the ratio of opposite branch resistance to the total resistance multiplied by the total current. A point where two or more than two components are joined.

The rule or formula derived from these known impedances to know the portion of total current through any parallel path is known as the current divider rule. R t Equivalent resistance of parallel resistors See formula below 133 Ω. Thus we can write the current division formulaas Example 13.

Current Division Rule Formula. We are interested to find the current flowing through resistor R x. The current in conductor is given by Ohms law as where Vis the voltage across each conductor.

You will notice that if we want to find current through any one of the resistances say R 1 the total current I is multiplied with the ratio of another resistance R 2 total resistance R 1 R 2. This tool calculates the current flow through each of up to 10 parallel-connected resistances connected to a current source.

I x I 2 Unknown current. We have discussed here current division rule and how to derive it. Thus from the equation 6 and 7 the value of the current I 1 and I 2 respectively is given by the equation below.

Where It is the equivalent resistance and it can be calculated by using the formula. The electrical current entering the node of a parallel circuit is divided into the branches. The formula for current divider law is now.

The two formulas above explain that how two currents are calculated. Current divider formula is employed to calculate the magnitude of divided current in the circuits. Find the current in the inductor and the current in the resistor.

I t Total current Incoming current at the node 10 A. The current divider rule will now become in our case. Circuits containing series and parallel connections-- Consider the circuit of figure 115.
