They now have evidence that there was knowledge of batteries and electrical power in ancient Rome. They of course don't know who discovered it, or what got in the way of further development is anybodies guess.
What else can I help you with?
Has a slight positive charge on one end and a slight negative charge on the other end?
Batteries will typically have a slight positive charge on one end and a slight negative charge on the other end. Polar substances act similarly.
What particles has a negative charge and which has a positive charge?
Negative charge = electron Positive charge = positron Positive charge = proton
Why do batteries have positive and negative energies?
Batteries have positive and negative terminals due to the flow of electric charge, which is driven by chemical reactions within the battery. The positive terminal, or cathode, attracts electrons, while the negative terminal, or anode, releases electrons. This difference in charge creates an electric potential that allows for the flow of current when the battery is connected in a circuit. Essentially, the positive and negative energies enable the battery to store and release electrical energy efficiently.
What charge electron charge positive or negative?
Electrons carry a negative charge to balance out the positive charge of the proton.
Does all matter have a negative or positive charge?
No, not all matter has a negative or positive charge. Matter can be neutral, meaning it has an equal number of positive and negative charges, such as in most atoms. Charged particles exist in matter, such as electrons with a negative charge and protons with a positive charge.
What is the difference between a negative and a positive?
positive ions carry positive charge and negative ions carry negative charge
Is an atom a negative charge or a positive charge?
An atom with positive charge is cation.An atom with negative charge is anion.
Which particle proton neutron or electron have a positive charge?
proton positive neutron neutral electron negative
When a proton is positive an electron is?
Negative. Protons have a positive charge while electrons have a negative charge.
Is b a negative or positive charge?
A positive charge
What part of an atom has a negative charge and what was a positive charge?
electrons = negative charge protons = positive charge neutrons = neutral charge
What is the opposite of a negative charge?
The opposite of a negative charge is a positive charge. Positive charges have more protons than electrons, resulting in an overall positive charge.
