Calculation:
We have two resistors connected in series. Let's call the 6 ohm resistor R1 and the 9 ohm resistor R2.
The total resistance in a series circuit is the sum of the individual resistances. So, the total resistance, RT, is given by:
RT = R1 + R2
Substituting the values, we get:
RT = 6 ohm + 9 ohm
RT = 15 ohm
The total resistance in the circuit is 15 ohms.
The power dissipated by a resistor can be calculated using the formula:
P = V^2 / R
Where P is the power, V is the voltage across the resistor, and R is the resistance.
Power dissipated by the 6 ohm resistor:
We know the voltage across the circuit is 120 V. Since the resistors are connected in series, the voltage across each resistor is the same.
So, the voltage across the 6 ohm resistor is also 120 V.
Using the formula for power, we can calculate the power dissipated by the 6 ohm resistor:
P1 = V^2 / R1
P1 = (120 V)^2 / 6 ohm
P1 = 14400 V^2 / 6 ohm
P1 = 2400 W
The power dissipated by the 6 ohm resistor is 2400 watts.
Conclusion:
The correct answer is not A, but option B - 576W.

Net resistance = 6+9=15 ohm
Current = V/R = 120/15=8
Power (6_^_ ) = i^2*r = 8*8*6=64*6=384 w
Current = V/R = 120/15=8
Power (6_^_ ) = i^2*r = 8*8*6=64*6=384 w
