In this lab, you will observe that the voltage measured across a battery connected in a circuit with current flowing is lower than the voltage measured across a disconnected battery. Why is this true

because all power is being stored in the battery instead of draining the battery getting a result of a smaller and smaller voltage put through the circuit  

Explanation:

say the battery  is 1.5 volts, in a circuit it is slowly decreasing the power output of 1.5 volts to 0 volts by using the power within the battery when you have the  battery disconnected  the voltage will remain the same as which you left it

the bal will not change its velocity.

answer

the arrows to the right of earth should point up.
