WebThe size of the phase angle will be determined by the ratio between resistance and capacitance. The series RC circuit vector is similar to the RL circuit in that it uses the common current element as the reference vector. WebNov 24, 2024 · What is the phase difference between current and voltage? It turns out that there is a 90° phase difference between the current and voltage, with the current reaching its peak 90° (1/4 cycle) before the voltage reaches its peak. Put another way, the current leads the voltage by 90° in a purely capacitive circuit.
