For the circuit shown below, the switch has been at position "A" for a long time. At 1-0 the switch will move from position "A" to position "B". Determine: a) The voltage V1(t) for t>0. b) The power absorbed by the 6 Ohms resistor at time equal to 1 second. 30 Volts + I From A to B @ t=0 A 6 Ohms B + 12 Volts 3 Ohms ww V1 еее 0.2 H +
