Final answer:
To find the power developed by the source, use the equation P = IV. The total power supplied by the source can be compared with the sum of the powers dissipated by the resistors.
Step-by-step explanation:
The power developed by the source can be found using the equation P = IV, where P is the power, I is the current, and V is the voltage. To find the power developed by the source, we need to know the current and voltage supplied by the source.
In order to calculate the total power supplied by the source, you need to consider the power dissipated by the resistors.
The power dissipated by each resistor can be found using the same equation P = IV, where I is the current passing through the resistor and V is the voltage drop across the resistor. The total power supplied by the source can be compared with the sum of the powers dissipated by the resistors.
