Question

Calculate P3 (in W). W (b) Find the total power (in W) supplied by the source. W Compare the total power with the sum of the powers dissipated by the resistors. (Consider two values to be equal if they are within 3% of each other.) The total power is less than the sum of the powers dissipated by the resistors. The total power is equal to the sum of the powers dissipated by the resistors. The total power is greater than the sum of the powers dissipated by the resistors.

Answer 1

Answer:

the principle of conservation of energy cannot be violated.

the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.

Explanation:

The power in an electric circuit is given by

         P == I V

In a circuit with several components (resistors) the power dissipated is the current by the voltage in each resistance, by the principle of conservation of energy the current in each resistance is the same if the circuit is in series and the current is the same if The circuit is in parallel, but cannot be greater than the current supplied by the power source.

Therefore, the power dissipated by the entire circuit is the sum of the power dissipated by each part, since the principle of conservation of energy cannot be violated.

When reviewing the answers, the correct one is: The total power is equal to the sum of the powers dissipated by the resistors.
