Use Ohm's Law to find the amount of current that would flow in a circuit that contains a 10 (V) source and a 4 k resistor.
a) Do the terms in Ohm's Law need to be manipulated to solve the problem? Explain.
b) In your opinion, would it be simpler to manipulate Ohm's Law to solve for the unknown variable and then insert the given values, or to insert the given values and the manipulate the equation to solve for the unknown? Explain.
c)Find the amount of current flow that would be generated by the given voltage source.

Shouldn't you be doing your own homework and not letting the people on the internet do it for you. Crack open that textbook.

You want to solve for I, the current. It is convenient to rearrange the equation so that the current is all by itself on one side of the equation. If you know algebra you could just drop everything in and work the answer without rearranging.
I would rearrange the equation to be I = E/R because then I have it the way I want before I clutter it up with numbers. If I had more than one current to find that would definitely be the best way.
I = E/R = 10/4000 = 2.5/1000 = 2.5 mA
