Class A objects tend to smolder for a long time, and the fire can very easily reignite as the CO2 dissipates. 3. Use plenty of water. A specifically Class A fire extinguisher is essentially water under pressure, so you can use large amounts of water from a sink if it''s the only thing you have available.

Strategy. We use Equation 9.1.4.2 to find the energy U1, U2, and U3 stored in capacitors 1, 2, and 3, respectively. The total energy is the sum of all these energies.

When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not necessarily the battery voltage.
