- How does water tension across a vast surface area work? If I break water tension 1000km away, is the water tension here in tact or weaker?
- It is in tact, surface tension is a local phenomenon
- What is the current and voltage of the electrical impulses between neurons
- A small but critical voltage (70 millivolts) can be measured between the inside and outside of a neuron cell membrane, but that voltage isn’t present between two neurons. No charged ions pass between neurons, so there is no current flow across a synapse.
