Graph for a fixed resistor
WebMay 8, 2015 · 1 In the textbook I'm using for physics it says that the charge left on the plates of a capacitor after time t, that is discharging through a fixed resistor, is Q = Q 0 e − t / τ where τ = R C is the time constant. This is also the equation for the potential difference across the plates after time t. WebIn a pure resistance the relationship between voltage and current is linear and constant at a constant temperature, such that the current ( i ) is proportional to the potential difference V times the constant of proportionality 1/R giving i = (1/R) x V. Here, the slope 1/R is nothing but the conductance.
