Answer:
no way I had that question too :-O anyways here's the answer

Answer:
Volume charge density: When the charge density is throughout the volume of a body, then the charge per unit volume is called volume charge density and it is represented by ρ.
∴ρ=
Hence the unit of ρ is Cm
−3
Example: If a charge q is uniformly distributed in the whole volume of a
sphere of radius R, then p =
=3q/4πR-3
For transfomers (robots in disguise), there are equations to help us solve these problems.
Here are the equations you need:
is our V primary,
is our V secondary,
is our number of loops on our primary and
is number of loops in our secondary.
Plugging our known values in, we can solve for the secondary voltage.
For current, we have another equation:
Just like before, we can plug in our known values:
Since we are told there are no losses, the input power must equal output power.
(0.5A)(1760V)=(220V)(4A) = 880W
