Problem Statement Solve the capacitor/capacitance problem: Irodov Problem 3.238 (Section 3.3: Electric Capacitance. Energy of Electric Field): This problem concerns capacitors with dielectrics: energy and force. The key is to apply the capacitance definition $C = Q/V$, find the field geometry, and compute stored energy $U = Q^2/(2C) = CV^2/2$. Capacitor geo Given Information Plate…

Problem Statement Analyze the circuit: Irodov Problem 3.303 (Section 3.4: Electric Current): This problem concerns rc circuits: charging and discharging. Electric current involves the ordered motion of charge carriers driven by an electric field. The macroscopic laws (Ohm’s law, Kirchhoff’s laws, Joule heating) connect the microscopic ca Given Information Resistance values $R_1, R_2, \ldots$ as…
