I really appreciate your videos and would like you to replace my IB Physics teacher. We don't have free health care in Texas but I think you may like the warm weather.
At 4:30, I understand that there is current flow from the electrode to the other electrode, but why is there also flow going back (why is there a cycle)? Thanks!!
@@yesman2407 IYou keep decreasing the variable resistor, and the current increases. When the internal resistance equals the variable resistor, 1.5 volts will be split equally across the internal resistance and the variable resistor. We can imagine decreasing the variable resistor to zero. Theoretically, (this is akin to Newton's first law) no voltage would be required to push a current through zero resistance. The resistance of the circuit would the the internal resistance, and there would be 1.5 volts across it.

We're having a warm winter here. Glad you appreciate the videos; they are intended to assist (not replace) what your teacher does!
Honestly, you're just the best!
Thank you, brother Christopher.
You are very welcome
GOD BLESS YOU!!!
Hi Chris, I was wondering if you can also define the internal resistance with reference to charge carriers
At 4:30, I understand that there is current flow from the electrode to the other electrode, but why is there also flow going back (why is there a cycle)? Thanks!!
Back along the wire or in the electrolyte?
Back along the wire, why would there be a flow there going back?
The free electrons are attracted to the postive charge build up.
what do you mean by load resistance and load voltage?
If we connect a device or a simple resistor or lightbulb across a battery, we would that the load.
How does current flow when the voltage across the variable resistor/the cell is zero?
Where are you refering to in the video?

@@donerphysics Thank you
Thanks for saving me!
@8:53 Isn't the current flowing in the wrong direction ?
That's true. I am not going to worry about it here, as I think by this point everyone knows current flows from the + to the - side of the battery.
@@donerphysics isn't + to - conventional flow? but actual electron flow is - to +?
