A constant current of 1 ampere is measured flowing into the positive reference terminal
Chapter 2, Problem 28(choose chapter or problem)
A constant current of 1 ampere is measured flowing into the positive reference terminal of a pair of leads whose voltage we’ll call \(v_p\). Calculate the absorbed power at t = 1 s if \(v_p(t)\) equals (a) +1 V; (b) −1 V; (c) 2 + 5 cos(5t) V; (d) \(4e^{−2t}\ V\), (e) Explain the significance of a negative value for absorbed power.
