Answer:
V₅ = 20 V
Explanation:
Given that
Total voltage ,V= 120 V
Given that resistor are connected in series that is why the total voltage drop will be summation of voltage drop in the all resistor.
V₁=Voltage drop on first resistor
V₂=Voltage drop on second resistor
V₃=Voltage drop on third resistor
V₄=Voltage drop on forth resistor
V₅=Voltage drop on fifth resistor
Therefore
V= V₁+V₂+V₃+V₄+V₅
120 = 35 + 28 + 22 + 15 + V₅
V₅ = 20 V
Therefore the voltage drop on the fifth resistor will be 20 V.
Answer:
The area of solar panel needed in Buffalo is 22.83 m²
The area of solar panel needed in Phoenix is 31 m²
Explanation:
<u>FOR BUFFALO</u>:
First we, calculate the the annual power requirement by dividing the energy by the time of 1 year.
Therefore,
Power Requirement = P = 6000 KWhr/(1 yr)(365 days/yr)(24 hr/day)
P = 684.93 W
Now, to calculate the area we use the formula:
Area = A = P/(Annual Insolation)(Conversion Factor)
A = 684.93 W/(200 W/m²)(0.15)
<u>A = 22.83 m²</u>
<u>FOR PHOENIX</u>:
First we, calculate the the annual power requirement by dividing the energy by the time of 1 year.
Therefore,
Power Requirement = P = 11000 KWhr/(1 yr)(365 days/yr)(24 hr/day)
P = 1255.7 W
Now, to calculate the area we use the formula:
Area = A = P/(Annual Insolation)(Conversion Factor)
A = 1255.7 W/(270 W/m²)(0.15)
<u>A = 31 m²</u>

Answer:
He probably tripped the wiring, when metal hits the electricity it creates a reaction that burns the wiring.
Explanation:
Answer:
<u>Eo = A/[-nB/A]^(1/n-1) + B/[-nB/A]^(n/n-1)</u>
Explanation:
<u>Step 1.</u>
Taking derivative of the equation with respect to 'r' we get:
d/dr(EN) = - A/r² - nB/r^(n+1)
Setting this equation to zero:
<u>Step 2.</u>
Solving for r:
- A/r² - nB/r^(n+1) = 0
A/r² + nB/r^(n+1) = 0
Ar^(n+1) + nBr² = 0
Ar^(n+1) = - nBr²
[r^(n+1)]/r² = - nB/A
r^(n+1-2) = - nB/A
r^(n-1) = - nB/A
Taking power 1/(n-1) on both sides:
r = [-nB/A]^(1/n-1)
This is the value of ro:
ro = [-nB/A]^(1/n-1)
<u>Step 3.</u>
Substituting value of ro in eqn we get value of Eo
<u>Eo = A/[-nB/A]^(1/n-1) + B/[-nB/A]^(n/n-1)</u>
