Ideal Op Amp 1. Input Resistance is very large, so input current is zero 2. V p =V n 3. Output Resistance is zero 4. 5 types of Op-Amps i) None-inverting ii) Voltage follower iii) Inverting iv) Summing v) Difference Capacitors C=Q/V ; I = C * dV / dt ; V = 1/C* ∫i dt ; W = .5*C*V 2 When adding in series, treat like resistors in parallel When adding in parallel, treat like resistors in series Inductors V = L di/dt ; i = 1/L* ∫V dt ; W = .5* L * i 2 When adding in series, treat like resistors in series
