The formula to calculate power loss is:
\[ \text{PL} = I_i \cdot V_i - I_o \cdot V_o \]
Where:
A power loss is defined as the total difference between the input and output power of an electrical circuit due to resistances throughout the circuit. The power is calculated by multiplying the current by the voltage.
Let's consider an example:
Using the formula to calculate the power loss:
\[ \text{PL} = (5 \times 12) - (4 \times 10) = 60 - 40 = 20 \text{ W} \]
This demonstrates that with an input current of 5 A and voltage of 12 V, and an output current of 4 A and voltage of 10 V, the power loss is 20 W. ✅
