Without removing the 5 µF capacitor, what can a technician add to correct the circuit? 4. In the figure below, if C, = C, = 2C; = 22.6 µF, how much charge C2 C3 is stored on each capacitor when V = 45 V? HHH 5. In the same figure as #4, C, = C, = C; = 16 µF. If the charge on C, is Q, 24µC, determine the charge on each of the other capacitors, the voltage across each capacitor, and the voltage across the entire combination. 6. In the same figure as #4, let V = 78 V and C, = C, = C; = 7.2 µF. How much energy is stored in the capacitor network?arrow_forwardTrue or False 1. The equivalent capacitors stores the same amount of charges but NOT THE SAME amount of energy when connected in PARALLEL. 2. A small time constant means that the capacitor charges and discharges VERY SLOWLY. 3. A good voltmeter is designed with a VERY LARGE resistance for it not to alter the voltage in the circuit when connected. 4. Time constant is equal to R / C. 5. A good ammeter is designed with a VERY SMALL equivalent resistance to avoid reduction of current when connected in a circuit.
