Question

. A constant current of 1 ampere is measured flowing into the positive reference terminal of a pair of leads whose voltage we’ll call vp. Calculate the absorbed power at t = 1 s if vp(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

Answer 1

Answer:

(a) 1W

(b) -1W

(c) 6.98W

(d) 0.541W

(e)Negative value of absorbed

power indicates that the object is

actually supplying power to some

other object. That is negative

absorbed power is equal to

positive supplied power.
