Today's Picture of the day says:
The common definitions of anode and cathode are based on the direction of current flow into or out of a device.Stars are “positive anodes in a galactic glow discharge”.
Current flow is the direction of the positive ion's flow, or the opposite direction of the flow of electrons. This is of course a matter of convention.
There are four parts to any situation involving anode and cathode.
1. A device (like a battery, or a power source)
2. The anode
3. The cathode
4. The circuit external to the device, being supplied by the device.
The terminal names can be reversed for example when a battery is being charged. Then the device is the charger and the battery is the external circuit.
So, what is this post about ?
The basic form of a solar(star) system has only three parts. IMO
1. The terminal at the core of the star.
2. The outer terminal which is the spherical outer boundary of the star system.
3. The spherical areas between these two, which includes photosphere, chromosphere, corona, and all the rest of
the solar environment.
Number three is not both the device and the circuit, or is it ?
IF IT IS BOTH AT THE SAME TIME
We need new names for the terminal places.
An ANODE sun needs a device and a circuit. ???
Attempting to think outside the box.
