What does the term passive reference configuration imply? a. passive reference configuration implies that the reference direction of the current is in the opposite direction of the reference direction of the voltage. b. passive reference configuration implies that the reference direction of the current is the same direction as the reference direction of the voltage.

b. Passive reference configuration implies that the reference direction of the current is the same direction as the reference direction of the voltage.

Explanation:

Term Passive reference configuration implies that current i flowing through the element voltage across which is v.

P= v×i

we say that power is absorbed or released by an element depends upon the sign of P. And This depends upon the sign of current entering and the voltage across the terminal. This is know as passive reference configuration.

If the current enters the negative end of polarity the power P= -v×i

therefore here option B is the correct answer.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
