A parallel circuit contains an AC voltage source of 3 Vrms, 100 Hz. The output of the voltage source is connected to a diode (1N4004). After the diode, connected in parallel are a 0.1uF capacitor and a 100 kohm resistor. Will the dc output voltage be higher or lower than the effective ac input voltage?
