If the current going through the inductor is 70sin 1000t and its inductance is 50mh.

Voltage drop across inductor. All you have to know to calculate the voltage across the inductor is l the inductance of the inductor which is expressed in units henry and the derivative of the current going through the inductor. Remember the voltage dropped across an inductor is a reaction against the change in current through it. So the voltage across the inductor is 180sin60t volts v.

As described by lenzs law the induced voltage will be opposed to the change in current. Then the voltage across the inductor v l will have an initial value equal to the battery voltage at time t 0 or when the switch is first closed and then decays exponentially to zero as represented in the above curves. However the voltage drop across the inductor v l will have a value equal to.

Therefore the instantaneous voltage is zero whenever the instantaneous current is at a peak zero change or level slope on the current sine wave and the instantaneous voltage is at a peak wherever the instantaneous current is at maximum change the points of steepest slope on the current wave where it crosses the zero line. Calculate the actual relationship between voltage and current across inductance through advanced online voltage across inductance calculator by applying the ohms law for an inductor formula. How much voltage the inductor will produce depends of course on how rapidly the current through it is decreased.

The inductor always opposing any change in current will produce a voltage drop opposed to the direction of change.

What is the voltage across an inductor if the current is 5cos120t and the inductance is 02h.
