How much power does a DC series circuit consume if R1 = 50 ohms, R2 = 100 ohms, R3 = 183.33 ohms, IT = 0.6 amperes, and ET = 200 volts?

To determine the power consumed by a DC series circuit, one can use the formula for power, which is the product of the current and the voltage (P = I × V). In a series circuit, the total resistance is the sum of the individual resistances (R_total = R1 + R2 + R3).

In this case, you would first calculate the total resistance:

R_total = R1 + R2 + R3 R_total = 50 ohms + 100 ohms + 183.33 ohms R_total = 333.33 ohms

Next, you can find the total voltage applied to the circuit, which is given as 200 volts. Since the current (IT) is also provided as 0.6 amperes, you can confirm that the circuit is functioning correctly by checking if the voltage drop across the total resistance matches the supply voltage.

The power consumed by the circuit can be calculated using the current and total voltage:

P = IT × ET P = 0.6 A × 200 V P = 120 watts

Therefore, the correct choice is 120 watts. This demonstrates the application of fundamental circuit principles—where power is directly a function of both current and
