You noticed that there was a y-intercept on your Ohm's Law graph. What is the physical meaning of the y-intercept? Try to explain why that value was detected on your circuit even when it was disconnected or turned off.
The y-intercept of the ohms law graph indicates the current. this represents the amount of voltage that is supplied. Even though the current is turned off, voltage is close but not zero, if the switch is open, the current is zero, but voltage is not.
TEACHER RESPONSE: It's the zero current!
