Electricity can be a simple as charge movement. That's a basic definition, and it can be expanded from there. But in its essential form, anything that can generate a voltage can "cause electricity" as a result. Let's look at things that generate a voltage. Triboelectric effect, a form of contact electrification, generates a voltage and causes charge movement by the simple act of separating two materials. (Anyone who takes a piece of plastic wrap off a roll causes this. That's where the static charge on the wrap comes from, and that's why it is a challenge to "make it behave" when trying to put it on something. Piezoelectric effect is the generation of voltage by applying mechanical energy to certain crystals or possibly ceramics. Pyroelectric effect. Heat causes charge movement, and this phenomena is directly related to Piezoelectric effect. Thermionic effect causes charge movement in response to thermal energy, to heat, but is different from pyroelectric effect. Photoelectric effect is the generation of a voltage by the application of photons (light) to a photosensitive material. Electrochemical action is what batteries are all about. Electromagnetic induction is extremely common. We use it everywhere in motors and generators as well as a broad variety of other things. Got links if you want them.

No, the Romans did not have electricity. Electricity was invented some 1,500 years after the Romans.
yes
no electricity was not a invention
Although Benjamin Franklin conducted an extensive research on electricity, he was not its inventor. Electricity can not be invented since it is a natural product. What he did prove was that lightning is a form of electricity.
It gets the power from the electricity lines.
Lightning can occur without clouds when there is a discharge of electricity between the ground and the atmosphere, often due to the buildup of static electricity in the air. This phenomenon is known as "ground-to-cloud" lightning.
Electricity.
After electricity reaches the muscles, it triggers the release of calcium ions within the muscle fibers. This causes the muscle fibers to contract and generate force, allowing movement to occur.
it is the tilt of the earth in the suns direction
electricity causes an electromagnetic field, also radiation.
There is no friction IN static electricity. However static electricity can be caused BY friction.
In nature there are two types of electricity positive and negative
Death
electricity is something that causes shocks
Electricity is the force of what causes static cling in a dryer.
Static electricity can occur when certain materials rub against each other, causing the transfer of electrons between the two surfaces. This transfer of electrons can build up a charge on the surfaces, resulting in static electricity. Common examples include when you walk on carpet and touch a metal object, or when you rub a balloon on your hair.
