D) charge on the positive plate E) plate separation 3. A dielectric slab is slowly inserted between the plates of a parallel plate capacitor while the capacitor is connected to a battery. As it is being inserted: A) the capacitance, the potential difference between the plates, and the charge on the positive plate all increase B) the capacitance, the potential difference between the plates, the charge on the positive plate all decrease C) the potential difference between the plates increases, the charge on the positive plate decreases, and the capacitance remains the same D) the capacitance and the charge on the positive plate decrease but the potential difference between the plates remains the same E) the capacitance and the charge on the plate increase but the potential difference between the plates remains the same 4. A 1.5-V battery is connected to a circuit and puts out a current of 0.45 A. How much power is putting out? ) 0.30 w B)0.68 w C) 3.3 W D) 5.0 w 0.67S E) 7.4 W proportionality constant for:

Explanation / Answer

3. Answer E , since battery is still connected, it will maintain the same potential difference, and therefore increase the charge, and increase the capacitance.

4. Power = V x I = 1.5x 0.45 = 0.68 W. Answer B
