An ammeter measures the current in a motor that raises and lowers a theatre curtain. The current is greater while the curtain is being raised than while it is being lowered.
Which statement describes the difference between the two current readings?
More charge passes a point in the motor circuit each second while the curtain is being raised
Charge is used up more quickly by the motor while the curtain is being raised
More charge passes through the motor in total whenever the curtain is being raised
More charge is present in the motor circuit while the curtain is being raised
