1. Using the definition C = Q/V, show that for a SERIES connection of capacitors:
1/C1/C1+1/C2. What does this equation mean? What happens to C as more and more capacitors are connected in series? 2. Using the definition C = QV, show that for a PARALLEL connection of capacitors: C = C1 + C2. What does this equation mean? What happens to C as more and more capacitors are connected in parallel?
Calculate the boiling point and freezing point of the following solutions:
1) 0.575 molal aqueous solution
