why inductance's current represent with di/dt?
ps) and how do you make image big...
Actually the Voltage is Ldi/dt. But I'm not sure that is all you are asking.
A constant voltage across an inductor will cause a constant change in current (di/dt) .... and vice-versa.
No idea about the images, but they expand when people click on them.
Make that an Ideal inductor - real inductor's restive elements can have V with no dI/dt.... fine for circuit analysis, but in a real circuit this should always be considered.
Separate names with a comma.
