When the voltage is increased does the speed of electrons increase or does the electron dens...

Voltage is the amount of energy in joule in every charge of 1 coulomb moving through the wire. Increase in current translates to increase in speed of electrons moving past our reference point. …

Empty and fresh battery in series

A battery works by harnessing an electric potential to drive electrons through a conductor. When two batteries are in series, there's a sandwich of different potential regions in the pattern negative- …

Why isn't there any current in the primary if secondary circuit is opened in a transformer?

Adding a resistor along the primary reduces the voltage, reaching the induction coil by dissipating some energy as heat. …

How does a load/resistor affects a Transformer?

Just like how the induction coil in an induction motor feels the resistance of the load on the rotor. A magnetic field moving relative to a charged particle or vise versa experiences a force on it equ …

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

Voltage is defined to be the energy required to raise charges to a particular potential OR the amount of energy (potential or dynamic) per coulomb of charge in the system, commonly known as the potential … If we consider all sources of electricity in existence, we can conclude that the potential difference (~voltage) determines how much current flows through a wire of a particular resistance. …

Potential in open branch of a parallel circuit with grounding

You're right there isn't current through the branch leading to $Q$, and there isn't "voltage" also based on $V=IR$. Voltage doesn't always means the potential difference or potential. …

How do I create a highly conductive vapor cloud? [closed]

I'm working on a project that requires that I create an electrically conductive gas cloud that can conduct voltages as low as 1.5v from a regular double A battery. I've been looking into using mecury …
