The voltage and current at the terminals of the circuit element are zero for t<0 and t>40s. in the interval between 0 and 40 s the expressions are
v=t(1-.025t) V, 0i=4-.2t A, 0
a.)at what instant of time is the power being delivered to the circuit element maximum?
b.)what is the power at the time found in first part?
c.)at what instant of time is the power being extracted from the circuit element maximum?
d.)what is the power at the time found in last part?
e.)calculate the net energy delivered to the circuit at 0, 10, 20, 30, 40s.
