Energy and Electrical Power

Physics

Not quite remember

I easily remember

Relationship between E, V, I and, t

E=V I t

Relationship between P ,V and, I

P = VI

Energy consumed for electrical devices, E

E = Pt

Cost of consumption

Total cost=E×Cost per kWh

P = VI

Equation relationship between power, voltage and current

E = VIt

Equation of relationship between energy, voltage, current, and time

Equation of relationship between power, current, voltage and resistance

P= I x IR or P = IV

E=Pt

is the equation to determine the energy used by an electrical device

Way to calculate the amount of electric energy

Calculate by using equation of E=VIt or E=Pt

Total cost=E×Cost per kWh

The equation to determine the total cost of electric energy consumption.
