A resistor is a deliberate obstacle. Inside, carbon or metal film forces electrons to bounce around, converting electrical energy into heat (which is why resistors get hot).
A transistor has three legs. A small amount of current/voltage on the "Base" (Gate) controls a large amount of current flowing between the "Collector" and "Emitter" (Drain and Source). electrical components and their functions
Next time you look at a circuit board—your phone, your car, your microwave—don't see a mess of plastic and metal. See the Resistor holding back the flood. See the Capacitor smoothing the storm. See the Transistor thinking faster than thought. A resistor is a deliberate obstacle
An inductor is simply a coil of wire. When current flows, it creates a magnetic field around the coil. When the current tries to stop, that magnetic field collapses and pushes the current to keep going . A small amount of current/voltage on the "Base"
