The two ends of a 3.0-W resistor are connected to a 9.0-V battery.What is the current through the resistor?
A)27 A
B)6.3 A
C)3.0 A
D)0.33 A

We can use Ohm's Law to calculate the current through the resistor:

I = V/R

where I is the current, V is the voltage, and R is the resistance.

Plugging in the values given in the problem, we get:

I = 9.0 V / 3.0 Ω = 3.0 A

Therefore, the answer is choice C.
