Assignment:
Question 1. What is the energy in a 2 F capacitor at t = pi seconds if v(t) = cos(2t)?
Question 2. What is the energy in a 10 H inductor at t = pi seconds if i(t) = cos(2t) ?
Question 3. The current flowing through a 1 H inductor is i(t) = 10*cos(20t) amps. Find the voltage.
Question 4. The voltage across a 2 F capacitor is v(t) = 20*e^(-4t) volts. What is the instantaneous power?
Question 5. The current flowing through a 2 H inductor is i(t) = 5*cos(2t) amps. What is the voltage?
Question 6. The charge in a 2 F capacitor varies as q(t) = 20*e^(-4t)*sin(2t) C. What is the voltage?
