# Homework Help: Finding Current given kilo-ohms and volt

1. The problem statement, all variables and given/known data

What is the current in a 46 kilo ohm resistor with 150V across it?

Given : 46 Kilo ohms
150 V

Answers has to be in Amperes

2. Relevant equations

Use Ohm's Law R = (V/I)

3. The attempt at a solution

I converted the kilo ohms back to ohms so 46 * 10 ^ 3 is 46,000 ohms. Divide 150 by 46,000 ohms and I get .003 as the answer. This answer is absurd but I converted the kilo ohms to ohms. I dont see where I went wrong. Seems like an easy question. =/

Why do you think the answer you got is wrong?

All of my answers from my Physics homework usually have a few digits before the decimal. This cannot be right.

Why not give the answer in milliamperes ?

Don't forget sig. figs.

Then you do get an answer that's a small fraction of 1 Ampere.
