A211-ω and a 221-ω resistor are connected in series across an unspecified power supply. if the current through the 211-ω resistor is 0.22 a, what is the exact current (in a) through the 221-ω resistor? do not include units with your answer.

0.22 (A)

Explanation:

Two resistors are connected in series when they are connected in the same branch of the circuit. When this occurs, we have the following:

- The current flowing through each resistor is the same (1)

- The total voltage of the circuit is the sum of the voltage drops across each resistor

- The total resistance of the circuit is equal to the sum of the individual resistances:

So, given statement (1), in this case the current flowing through each resistor is the same, so the current flowing throught the 221-Ω resistor is also 0.22 A.

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
