As the switch S is closed in given figure, current in. At any instant t. Inductor will behaves as simple wire. Consider a circuit containing a resistance R, an inductance L, a two way key and a battery of e. When the switch S is connected to a, the current in the circuit grows from zero value.

If a circuit containing a pure inductor L and a resistor R in series with a battery and a key then on closing the circuit current through the circuit rises exponentially and reaches up to a certain maximum value steady state. If circuit is opened from it's steady state condition then current through the circuit decreases exponentially. Please Wait you are being redirected You need to login to perform this action.

A circuit with resistance and self-inductance is known as an RL circuit. Notice its similarity to the equation for a capacitor and resistor in series see RC Circuits. This gives. The circuit then becomes equivalent to a resistor connected across a source of emf. The solution to this equation is similar to the solution of the equation for a discharging capacitor, with similar substitutions. The current at time t is then. If the time of the measurement were much larger than the time constant, we would not see the decay or growth of the voltage across the inductor or resistor. ## RL circuit

Learning to mathematically analyze circuits requires much study and practice. Typically, students practice by working through lots of sample problems and checking their answers against those provided by the textbook or the instructor. While this is good, there is a much better way. For successful circuit-building exercises, follow these steps:. One way you can save time and reduce the possibility of error is to begin with a very simple circuit and incrementally add components to increase its complexity after each analysis, rather than building a whole new circuit for each practice problem. Another time-saving technique is to re-use the same components in a variety of different circuit configurations. It has been my experience that students require much practice with circuit analysis to become proficient.

Consider a circuit containing an inductance L and a resistance R connected in series with a d. Let the current in the circuit at any instant t be I. As the current increases, the magnetic field surrounding the inductor increases. The flux passing through the inductor changes and an e. This e.
