If we find the capacitance for the series including C 1 and C 2, we can treat that total as that from a single capacitor (b). This value can be calculated as approximately equal to 0.83 μF. With effectively two capacitors left in parallel, we can add their respective capacitances (c) to find the total capacitance for the circuit.
