Inductors In Series And Parallel

V l1 v l2 v l3 v ab etc in the following circuit the inductors l 1 l 2 and l 3 are all connected together in parallel between the two points a and b. Inductors in parallel are inductors that are connected side by side in different branches of a circuit.

Just like resistors or capacitors you can combine inductors in series or parallel within an electronic circuit.

Inductors in series and parallel. So it stands to reason connecting inductors in parallel should decrease the total inductance. In a series circuit the current that flows through each of the components is the same and the voltage across the circuit is the sum of the individual voltage drops across each component. The definitive measure of inductance is the amount of voltage dropped across an inductor for a given rate of current change through it.

Inductors are said to be connected in series when they are daisy chained together in a straight line end to end. You can see that the inductors are in parallel because they are all on their own separate branches in the circuit. Inductors can also be combined in parallel circuits.

Below is a circuit where 3 inductors are in parallel. Inductors are said to be connected in parallel when two terminals of an inductor respectively connected to each terminal of other inductors or inductor. Inductors in parallel when inductors are connected in parallel with one another the reciprocal two or more i ors or product over sum two inductors formula can be used to find total inductance whih will always be less than the smallest inductors value 14 1l2 14 for the circuits in figure 8 21 a and wution.

When inductors are connected in series the total inductance is the sum of the individual inductors inductances. Note however that for the calculations to be valid the inductors must be shielded. Then inductors in parallel have a common voltage across them and in our example below the voltage across the inductors is given as.

This is just like the equivalent resistance of parallel connected resistors. To understand why this is so consider the following. When inductors are connected in parallel the reciprocal of the equivalent inductance of the combination will be the sum of the reciprocal of individual inductances.

However there are certain rules for connecting inductors in series or parallel and these are based on the fact that no mutual inductance or magnetic coupling exists between the individual inductors. In a parallel circuit the voltage across each of the components is the same and the total current is the sum of the currents flowing through each component. Then you can use simple equations to calculate the total inductance of the circuit.

Similar to the parallel connection of resistors the total inductance in parallel connection of inductors is somewhat lesser than smallest inductance of an inductor in that connection. Connecting inductors in series increased the total inductance. Just as series inductors act like series resistors parallel inductors act like parallel resistors.
