Electric Power Loss Calculation

How do you calculate the power loss in watts of a conductor?

1) By using the formula P = I × V

2) By using the formula P = I / V

3) By using the formula P = V / I

4) By using the formula P = I + V

Answer:

The power loss in watts of a conductor can be calculated using the formula for electric power, which states that power (P) is equal to the current (I) flowing through the conductor times the voltage drop (V) across it, P = I × V.

Electric power loss in watts is an important calculation in electrical engineering to determine the efficiency of a conductor. The formula to calculate power loss is P = I × V, where P represents power loss in watts, I is the current in amperes flowing through the conductor, and V is the voltage drop across the conductor in volts.

For example, if a conductor carries a current of 24A and experiences a voltage drop of 7.20 volts, the power loss can be calculated as follows:

Power Loss = 24A x 7.20V = 172.8 watts.

When comparing the calculated power loss with the given options, the closest answer is 175 watts. Therefore, the correct answer is 1) 175 watts.

In conclusion, understanding how to calculate power loss in watts is crucial for ensuring the efficiency and safety of electrical systems. By using the appropriate formula and values for current and voltage drop, engineers can determine the power loss in a conductor accurately.
