Question

Two capacitors , CA = 2 CB , are connected in parallel : both tops to battery + , both bottoms to battery ? . Which of the following is true? Answer a. CA stores twice the separated charge , at half the Voltage , and equal amount of Energy , as CB. b. CA stores twice the Q , at the same Voltage , and twice as much Energy as CB. c. CA stores the same Q , at the same Voltage , and same Energy as B. d. CA stores equal Q , at half the Voltage , and half as much Energy . e. CA stores equal Q , at twice the Voltage , and twice as much Energy . f. CA stores equal Q , at equal Voltage , and twice as much Energy .

Explanation / Answer

Given, CA=2CB Vab=QA/CA=QB/CB QA= CA*Vab =2*CB*Vab = 2*(CB*Vab) =2*QB therefore, CA stores twice the separated charge In parallel, same voltage exists Energy,U= 0.5*Q*V UA=0.5*2QB*V=2*UB Therefore, energy in CA is twice as much Energy as CB. OPTION (b)CA stores twice the Q , at the same Voltage , and twice as much Energy as CB.
