The switch in the circuit of Fig. 8.91, often called a make-before-break switch (since during switching it briefly makes contact to both parts of the circuit to ensure a smooth electrical transition), moves to position b at t = 0 only after being in position a long enough to ensure all initial transients arising from turning on the sources have long since decayed. (a) Determine the power dissipated by the 5 Ω resistor at t = 0−. (b) Determine the power dissipated in the 3 Ω resistor at t = 2 ms.
