Suppose a circuit contains an electromotive force (a battery) that produces a voltage of E(t) volts (V), a capacitor with a capacitance of C farads (F), and a resistor with a resistance of Rohms (N). The voltage drop across the capacitor is where Q is the charge (in coulombs), so in this case Kirchhoff's Law gives RI + 8 = E(t). Since I we have er et de 2 – EC). ae dt Suppose the resistance is 3082, the capacitance...
