Does Ohm's law $V = IR$ mean voltage causes current, or does it just say that voltage and current are related?

When the voltage is increased does the speed of electrons increase or does the electron density increase?

How does resistance convert voltage to current?

Why isn't there a minus sign in Ohm's law, $V = IR$?

Why is there an induced EMF in a plastic ring?

What's the reason behind the current remaining the same after passing by a resistance?

Kirchhoff's Voltage Law in a General Electromagnetic Field

At an atomic level, what happens when you connect two batteries in series so that their voltages are added?

How should I think about voltage and power?
