How might circuits be used to make a device or a home more energy efficient

Physics
1 answer:
Anastaziya [24]4 years ago
4 0

Answer:

Circuits can be designed to turn on lights when a person enters a room and to turn them off after people have left. They can regulate and control heating and cooling systems to create desired air temperatures in houses and buildings. They can tell your computer when to turn off the screen if it has not been used in a while

A wire 6.60 m long with diameter of 2.05 mm has a resistance of 0.0310 Ω.
Alex73 [517]

Answer:

1.551×10^-8 Ωm

Explanation:

Resistivity of a material is expressed as shown;.

Resistivity = RA/l

R is the resistance of the material

A is the cross sectional area

l is the length of the wire.

Given;

R = 0.0310 Ω

A = πd²/4

A = π(2.05×10^-3)²/4

A = 0.000013204255/4

A = 0.00000330106375

A = 3.30×10^-6m

l = 6.60m

Substituting this values into the formula for calculating resistivity.

rho = 0.0310× 3.30×10^-6/6.60

rho = 1.023×10^-7/6.60

rho = 1.551×10^-8 Ωm

Hence the resistivity of the material is 1.551×10^-8 Ωm
