The merry-go-round has a freewheeling diode built in, in that it has a bearing in the middle which allows it to keep spinning unhindered when you’re not actively pushing it. Translating this into electronics, in our circuit Q1 is the switch (driven by the PWM), L1 is the inductor, ...
A fixie bike, or fixed gear bicycle, is a single-speed bike with that single gear fixed in place. This means that, as you pedal forward, the bike will move forward, and when you pedal backward, the bike will move backward. There is no “free-wheeling” (or “coasting”) on a fixed...
There is just a slight difference between the coil constructions such that the freewheeling diode in the DC coil prevents de-energizing and back EMF. Solid-State Relays The use of semiconductors in solid-state relays differs from electromagnetic relays. It works on isolating the low-voltage ...

If you are in the office, keep clear of furniture on wheels that could come freewheeling your way during any tremor. If you are out on the street, try to head to open spaces or gardens, away from tall buildings, and try to avoid old-looking structures for newer concrete ones. ...

By open collector, we mean a collector that is unattached to anything. It's just open. In order for an open collector output device to work, the open collector has to receive sufficient power. In order to understand this, you have to understand NPN transistors. In order for an NPN transi...
by good non-linear characteristics (I=non-linear coefficient α in CUα), large current capacity (～2KA/cm2), low normal leakage current (10-7～10-6A), and low residual voltage, the response time to instantaneous overvoltage are fast (~10-8s), and there is no freewheeling. ...
