Question

Why does an inductor resist a sudden spike in current when you first flip a switch?

Accepted Answer

An inductor is just a coil of wire. When electricity starts flowing through that coil, it creates a magnetic field. Think of this like pushing a heavy shopping cart; it takes a moment to get it moving because of its weight. As the electricity tries to rush into the wire, that growing magnetic field fights back by creating its own force that pushes in the opposite direction. This opposing force acts like a speed bump for the electricity. It forces the current to start slow and climb up gradually instead of jumping to full speed all at once. Once the magnetic field is fully formed and steady, the inductor stops fighting and just lets the power flow through. The coil basically hates change and tries to keep the amount of current exactly the same as it was a split second before.
