The differential equation R+=0 describes the charges P coulombs at time t (in seconds), where C and R are the capacitance (in farads) and resistance (in ohms). respectively. (a) Solve the equation for P. given P = P₁ at t = 0. (b) Given the capacitance and resistance of a circuit to be 6.5 x 10 °F and 225 x 10³0. respectively. After 0.29 seconds the charge falls to 7 coulombs. Calculate the initial charge. Then, determine the charge after 1.5 seconds.
