A light bulb used in a 3.0 volt flashlight has a resistance equal to 9.0 ohms. What is the current (in Amps or in A) in the bulb when it is switched on?
Added by Samuel M.
Step 1
Ohm's Law states that V = I * R, where V is the voltage, I is the current, and R is the resistance. Given that V = 3.0 volts and R = 9.0 ohms, we can rearrange the formula to solve for I: I = V / R Show more…
