The unit of the product of resistance and capacitance is equal to the unit of time. (Option a).
- The Second is the product of resistance and capacitance.
- If Q denotes charge in coloumbs, and t denotes time in seconds then, C represents the capacitance in Farads. So according to ohms law, Resistance = V/I = volts/amp
- Capacitance = q/V = coulomb/volt OR (amp * sec/volt)
- Thus, the product of resistance and capacitance RC = (volt/amp)*(amp * sec/volt) = sec.
- The SI unit of time is also second.
