Question

If a resistor draws 1.2 * 10^-3 A of current from a 12 V battery, then what is the value of the resistor?

A. 10 ohms
B. 100 ohms
C. 1.0 kilo-ohms
D. 10 kilo-ohms

Answer 1

using the Ohm's law, we have:
I=12/(0.0012)=...amperes

Answer 2

oops..no amperes, Ohms

Answer 3

10,000?

Answer 4

I rewrite:
R=12/(0.0012)=...ohms

Answer 5

yes!

Answer 6

what does that convert to? divide by 1000? and the solution is 10 kilo-ohms? choice D?

Answer 7

that's right!

Answer 8

yay! thanks! :D onto the next!:)

Answer 9

:) ok!
