Use ohm’s law to find the resistance of the light bulb if you had a 20 volt battery and 0.57 amps of current. show your work for this question and test your answer with the gizmo.

Ohm's law states that the potential difference across a resistor is directly proportional to the current flowing through it:

where
V is the potential difference
I is the current
R is the resistor

In our problem, the potential difference is the voltage of the battery, V=20 V, and the current flowing in the light bulb is I=0.57 A. By using Ohm's law, we can calculate the resistance of the light bulb:

It would be 70 kmh just divide 420 by 6
