Determine the power dissipated in each of the resistors and the power entering the source. Express your powers in Watts. Remember that the power entering a two-terminal device is the product of the voltage across the device and the current through it in the associated reference directions. Write your answers in the spaces provided below.
sounds like you just have to plug in the numbers ...
Incomplete.
To determine the power dissipated in each resistor and the power entering the source, we need to know the voltage across each resistor and the current through each resistor.
1. Start by finding the voltage across each resistor. This can be done using Ohm's Law, which states that the voltage across a resistor is equal to the current through it multiplied by its resistance. If the current is known, simply multiply it by the resistance of each resistor to find the voltage across them.
2. Next, calculate the current through each resistor. If you know the total current entering the circuit, you can use the concept of parallel and series resistances to determine the current through each resistor. If the resistors are in series, the current through each resistor will be the same as the total current. If the resistors are in parallel, you need to use the concept of equivalent resistance to find the total current, and then use Ohm's Law to find the current through each resistor.
3. Once you have the voltage across and the current through each resistor, you can calculate the power dissipated in each resistor. The power dissipated in a resistor is equal to the product of the voltage across it and the current through it (P = V * I).
4. Finally, to find the power entering the source, you need to multiply the voltage across the source (which is equal to the voltage across the entire circuit) by the total current entering the circuit. This will give you the power entering the source.
Remember to express your answers in watts, which is the standard unit of power.
By following these steps and performing the necessary calculations, you will be able to determine the power dissipated in each resistor and the power entering the source.
