2. In this problem, we will analyze the energy and power relations for the charging capacitor circuit below. E i(t) R a t = 0 q(t) a. Calculate the total energy supplied by the battery to charge the capacitor. The instantaneous power p(t) delivered by the battery during the charging process is equal to E i(t). The current changes as a function of time and is given by i(t) = /et/RC. Find an expression for the total energy delivered by the battery by integrating p(t) from t = 0 to t→ ∞. b. Find the total energy dissipated in the resistor, R, during the charging process.

a. Calculate the total energy supplied by the battery to charge the capacitor. The instantaneous
power p(t) delivered by the battery during the charging process is equal to ε i(t). The current
changes as a function of time and is given by i(t) = -e-t/RC. Find an expression for the total
energy delivered by the battery by integrating p(t) from t = 0 tot → ∞o.
b. Find the total energy dissipated in the resistor, R, during the charging process.
