Question

1. A 7.7-?F capacitor is charged by a 150-V battery (see (Figure 1) a) and then is disconnected from the battery. When this capacitor (C1) is then connected (see (Figure 1) b) to a second (initially uncharged) capacitor, C2, the final voltage on each capacitor is 18 V .What is the value of C2? [Hint: charge is conserved.] Express your answer using two significant figures and include the appropriate units. C1 V (a) C1 C2 (b) 2. How much energy is stored by the electric field between two square plates, 7.9 cm on a side, separated by a 1.5-mm air gap? The charges on the plates are equal and opposite and of magnitude 16 nC . Express your answer using two significant figures and include the appropriate units.
