Then there is no return circuit. Without the return circuit, you have an end-fed antenna. There is a good reason why all conductors in...

Reflections only occur where there is an impedance mismatch. If the source is matched to the line, then there will be no reflection at...

You are using the term balance in two different ways. One as the maintenance of a gyroscopic orientation, the other as a dynamic...

They are the gaps between the woven wire of a coaxial outer braid, or the very narrow slots between the edges of a metal foil tape...

I believe you are talking about a coaxial transmission line. A signal current on the outside of the inner conductor, will be equal and...

That estimate for galactic source temperature is about right. When the Sun is quiet, it has lower flux than the galactic centre. The...

Assume maximum motor torque is proportional to maximum rated motor current. Then maximum forward motor current will flow for the first...

Was the antenna followed by three satellite TV amplifiers in series ? What was the RTL dongle plugged into, and controlled by ? Where...

Welcome to PF. Yes, you can post links...

Welcome to PF. The speeds seem reasonable. Why, and for how long, must it balance on two points? If the points are mounted on the...

I think you should mount the lens, fixed and aimed at the target, then track the Sun with a flat-mirror heliostat, mounted on a clock...

Ah got the wiring messed up, ok now; apologies for having wasted your time; thanks for your patience! Martyn

Further thoughts on a smoother operation, suggest replacing the syringes with two small peristaltic pumps, each controlled by hand. The...

There is a neutral wire only, no earth wire is provided on the transmission line. The neutral to earth bond is usually on each power...

Fuses protect conductors from fault overcurrents, that might melt the insulation or the wires. The ground path is bonded to neutral...
