HPHY 253 Workout 28a Capacitive and Resistive Networks Dr. A. E. Bak Name A capacitor is a combination of two conductors, each carrying the same amount Q of charge, but of opposite sign. The potential di/erence, between the positive and negative terminals of a capacitor, is given by V + V = Q C ; where C is the capacitance of the capacitor. For a set of capacitances f C k : k = 1 ; 2 ; 3 ;:::;N g series network: 1 C eq = N X k =1 1 C k ; parallel network: C eq = N X k =1 C k ; where C eq is the network±s equivalent capacitance. A resistor is a conducting device that primarily obeys Ohm±s law. Consequently, the potential di/erence, between the positive and negative terminals of a resistor, is given by V + V = IR ; where I is the current in the resistor and R is the resistance of the resistor. For a set of resistances f R k : k = 1 ; 2 ; 3 ;:::;N g series network: R eq = N X k =1 R k ; parallel network: 1 R eq = N X k =1 1 R k ; where R eq is the network±s equivalent resistance. 1. 26 : 12 . Two capacitances C 1 = 5 : 00 and C 2 = 12 : 0 are connected in parallel, and the resulting combination is connected to a 9 : 00 - V battery. (a)
