Question

Refrigerator power consumption in thermodynamics formula

Answer 1

Answer:

Power is basically given by, P = VI. Where V is the voltage and I is the current.

In series combination, the current (I) through each component is same. If R is the resistance of one of the components, then the power dissipated across this component can be written as,

P = VI = (IR)I = I2R

In parallel combination, the voltage (V) across each branch is same. If R is the resistance of one of the branches, then the power dissipated across this branch can be written as,

P = VI = V(V/R) = V2/R

Answer 2

Answer:

Explanation:

The efficiency of a refrigerator or heat pump is given by a parameter called the coefficient of performance (COP). The COP of a refrigerator is given by the following equation: COP = Desired Output/Required Input = Cooling Effect/Work Input = QL/W.
