PHYS 315 HWK on Capacitors Name:____________________________ Capacitor, also known as a condenser is a device where electrical charge can be stored. Capacitance is the capacity of a capacitor to store charge. The capacitance, of a capacitor is C, defined as the magnitude of the charge stored on one plate, per unit potential difference, q V. _____________________________________________________________________ 1) In Fig. , a 20.0 V battery is connected across capacitors of capacitances = = 3.00 and C1 C6 C3 μF = = 2.00C2 = 2.00C4 = 4.00 What are (a) the equivalent capacitance of the capacitors and C5 Ceq μF.
