Acamcorder has a power rating of 11 watts. if the output voltage from its battery is 8 volts, what current does it use?

The camcorder uses a current of 1.4 A.

P = VI

I = P/V = 11 W/8 V = 1.4 A

Note: The answer can have only one significant figure because that is all you gave for the voltage. However, I calculated the current to two significant figures.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
