WebSep 17, 2015 · If the resistor and capacitor is connected to a DC source, then it is neither leading nor lagging. If it is connected to an ac source, then the reactive part of the impedance will be capacitive overall (since no inductors are present) and hence the current will lead the voltage. (leading power factor). Answer link WebJul 6, 2024 · The voltage which leads or lags is the same voltage referred to by I(t) = CdV(t) dt which comes from the derivative of V(t) = Q(t) C = 1 C∫t t0I(τ)dτ + V(t0) Therefore the voltage which lags is the voltage drop across the capacitor because the charges are added above to the plates of the capacitor so the voltage refers to it. cytiva wave bioreactor https://rooftecservices.com
