Answer:
The cost of energy is 0.29$.
Explanation:
Given that,
Voltage V= 12 V
Charge Q= 160 A-h
We need to calculate the energy
Using formula of energy
[tex]E = Pt[/tex]
[tex]E =VIt[/tex]
Where, E = energy
I= current
V = Potential
t = time
Put the value into the formula
[tex]E = 12\times160\times3600[/tex]
[tex]E =6.9\times10^{6} J[/tex]
The cost of this energy at 0.15/kwh
[tex]Total\ cost = Energy\times 0.15 kwh[/tex]
Here, Energy = power x time
In units,
[tex]J=watt\times s[/tex]
But , Energy in 1 hour is:
[tex]E = 1920\ J[/tex]
So, The cost of this energy is
[tex] Total\ cost =1920\dfrac{\times0.15}{1000}[/tex]
[tex]total\ cost = 0.29\$[/tex]
Hence, The cost of energy is 0.29$.
