Use these equations here for this one. simply re-arrange to solve for the value you are missing:
I = current
E = volts
R = resistance
Power = watts

Equations
E = I x R
Power = I x E
Power = I^2 x R
Power = E^2 / R

Solving for I = 1.16Amps

Red stars have rays hundreds of times larger than the sun, literally being the biggest stars in space. Despite their gigantic size, these stars have low density.

A positively charged atom has _____. lost electrons lost protons gained electrons gained protons
IrinaK [193]

A positively charged atoms has lost electrons.

Electron are easy to remove from the atom, electron are of negative charge. Initially atom is neutral that is the charge of electron is equal to the charge of the proton, when atom loose some of its electron, the net charge of electrons is less than the net charge of the Protons, which makes the atom positively charged.
