RC is a component symbol in electrotechnics, which represents the series connection of resistance and capacitance in the circuit.

Where r stands for resistance and c stands for capacitance.

This symbol is often used in circuit diagrams and can be used to design and analyze various circuits, such as RC filters.

Resistance and capacitance are one of the most basic components in the circuit. Their series connection can produce specific circuit response, which can be used in signal filtering, waveform shaping and other applications.

Therefore, the significance of electrical component symbol RC is very important.
