WebThe op amp represents high impedance, just as an inductor does. As C 1 charges through R 1, the voltage across R 1 falls, so the op-amp draws current from the input through R L. This continues as the capacitor charges, and eventually the op-amp has an input and output close to virtual ground because the lower end of R 1 is connected to ground.
