What would be the total power consumed by the circuit as shown in figure "A" of the illustration if the source voltage is 12 volts, the resistance for R1 is 470 ohms, the resistance of R2 is 330 ohms, and the resistance of R3 is 800 ohms? Illustration EL-0032
AI Explanation
The correct answer is C) 360 milliwatts.
To calculate the total power consumed by the circuit, we can use the formula P = V^2 / R, where P is the power, V is the source voltage, and R is the resistance.
For the given circuit, the total resistance is the sum of the individual resistances: R1 (470 ohms), R2 (330 ohms), and R3 (800 ohms), which equals 1600 ohms. Plugging the values into the formula, we get P = (12V)^2 / 1600 ohms = 144 / 1.6 = 360 milliwatts.
The other options are incorrect because they do not accurately reflect the total power consumed by the circuit given the provided resistance values and source voltage.
