I can use the multimeter but I just want to find out using the formula.Any problem using a Ammeter or Millammeter?
I looked that link, that is the calculation for the RL circuit. In my circuit the single inductor is connected across the DC source. I am looking the formula so that I can find out the current through inductor
So I don't know time and I have find out the current. Should I have to suppose the timeE=10, L=1. Use the formula to find di/dt.
di/dt means 'the rate of change of current with time'. If you found one (non-zero) value of the current that must have been at one specific time, unless the current had reached a value limited by the resistance of the inductor.I have find out the current. Should I have to suppose the time
givendi/dt means 'the rate of change of current with time'. If you found one (non-zero) value of the current that must have been at one specific time, unless the current had reached a value limited by the resistance of the inductor.
That equation is not true when V and i have reached their steady state values. As you know, steady state means nothing is changing, and so di/dt will be zero for all future time and the value of L will be irrelevant, thus:Now I can understand and I can find out the energy stored in inductor
E=1/2Li*i
E=0.5*1*50*50
E=1250 joules
Power P=Li*di/dt
P=1*50*10
P=500W
Is this calculation is correct?
An inductor is NOT non-linear element.Hello
I need help to understand the basic concepts of inductor. Suppose 1h inductor is connected across 10v battery. Inductor is non linear element it change the value of current over the time. How to find out current through inductor?
What energy are you trying to calculate? There are different energy questions that could be asked.Power in AC circuit
P=i*i*XL
P=0.265*0.265*377.11
P=0.2648w
How to calculate energy in AC circuit
OK my mistakeAn inductor is NOT non-linear element.
What is your math background like? Have you seen any calculus yet? Do you understand exponentials and logarithms?
