Question
The figure shows a circuit containing an electromotive force, a capacitor with a capacitance of C farads (F), and a resistor with a resistance of R ohms (2). The voltage drop across the capacitor is Q/C, where Q is the charge (in coulombs), so in this case we use the Kirchhoff's Law.
+ = E (t)
But I = dQ/dt, so we have the formula below.

= E (t)
Suppose the resistance is 20 n, the capacitance is 0.01 F, and a battery gives a constant voltage of 100 V.
(a) Draw a direction field for this differential equation. (Do this on paper. Your instructor may ask you to turn in this sketch.)
(b) What is the limiting value, Q of the charge?
Q =
(c) What is an equilibrium solution?
Q =
(d) If the initial charge is Q(0) = 0 C, use the direction field to sketch the solution curve. (Do this on paper. Your instructor may ask you to turn in this sketch.)
(e) If the initial charge is Q(0) = 0 C, use Euler's method with step size 0.1 to estimate the charge, Q after half a second, Q(0.5). (Round your answer to the nearest hundredth.)
Q(0.5) =
