The current (in amperes) at time t (in seconds) flowing in the circuit in Figure 20 is given by Kirchhoff ’s Law:

i(t) = Cν'(t) + R⁻¹ν(t)

where ν(t) is the voltage (in volts, V), C the capacitance (in farads, F), and R the resistance (in ohms, Ω).

Assume that R = 200 Ω but C is unknown. Use the following data and the SDQ to estimate ν'(4), and deduce an approximate value for the capacitance C.
