The impedance of a resistor stays constant with frequency. For a capacitor, its impedance get smaller and smaller as frequency goes up.

The impedance of a resistor stays constant with frequency. For a capacitor, its impedance get smaller and smaller as frequency goes up.If R and C are in series, at 0 frequency the capacitor has infinite impedance (1/jwC = infinity), so it acts like an open circuit (we say a capacitor blocks DC current). The Resistor will have zero current and therefore zero voltage. All the voltage will appear across the capacitor.

All the voltage will appear across the capacitor.As frequency rises, more voltage will appear on R, and less and less on C, until at super high frequency the capacitor will seem to disappear and all the voltage is across R.
