current through inductor - All About Circuits
2008年10月22日 · The inductor would oppose the current initially.so zero current.and at steady state say a constant current flows.In between (though a very small time) will it be a straight line(i.e) a line with slope 1 if voltage is 1v and inductance is 1H according to the equation i=(1/L)*(integral(V dt)).
Inductor with constant current source - Electrical Engineering …
2018年12月8日 · Solving For Vb (Voltage across the inductor given a charging current of 10 amps and a time constant of 1.2H/10Ohms=.12=tau then at tau=1 or at the time T=.12s solving for Vb gives you a back EMF of 40-Volts and solving for current through inductor giver you 6 Amps. The website does the calculation for you. Gives good explanations too:
AC through Inductor - Electrical Engineering Stack Exchange
2017年7月11日 · Putting the two together, if you pass a DC current through an inductor, you get a steady magnetic field and nothing else happens. If you pass AC through it, you generate an alternating magnetic field. But an alternating magnetic field turns it into a generator, which generates a voltage to oppose your current.
Current through inductor - Electrical Engineering Stack Exchange
2015年10月8日 · \$\begingroup\$ In very simple terms, you simply can't have an abrupt change in current through an inductor. If you try to change the current quickly (eg by removing a voltage source) it just generates higher and higher voltages until something gives - sparks, insulation failure, or damage to what is driving it.
current - Inductor in DC circuits - Electrical Engineering Stack …
2023年9月30日 · It says that there is simply a constant of proportionality between voltage across an inductor, and rate of change of current through an inductor, called the inductance. It says nothing about causation. It is just as true to say the voltage causes the current to change, as it is to say that the current change causes the voltage.

circuit analysis - Continuity of a current through an inductor ...
2020年12月24日 · According to this website, the current through an inductor is always continuous unless there is an infinite voltage or current. but simulate this circuit – Schematic created using CircuitLab Now I know that the circuit was working before t=0 so the current on \$ i_{L1}(0^-)=10[A] \$ and \$ i_{L2}(0^-)=0[A]\$ and at t=0 they are connected in ...
how to find out current through inductor in DC circuit?
2016年8月4日 · If the applied voltage is 10v AC with 60Hz signal than I am trying to find out current through inductor Inductive reactance XL=2*3.14*f*L XL=2*3.14*60*1 XL=377.11ohms Now I know the Inductive reactance than I can calculate current through indctor I=V/XL=10/377.1=0.0265A
How to find current through inductor when connected in series …
2021年5月26日 · This voltage will be presented all rest of time so the R will take 1A from inductor current. The inductor current rate is 2V/3H = 0.67A/s now so after 2sec it will be incresed by 1.34A. Adding together with current at t=1s the inductor current at 2s after releasing switch is 2.34A. The diode current is 1A less due to constant R current, so 1.34A.
Inductor current - All About Circuits
2020年9月22日 · Two equations for the current through the inductor can be the V/L=∆I/∆T voltage divided by the inductance equals the change in current divided by the change in time and L/R for the time constant with about 3-5 time constants allowing the inductor to carry the current of V/R.
