All Resistors are in parallel. Because The current divide in each branch and voltage across all resistor are same.

If the two leads of resistor is connected to the leads of another one. Then we can say that resistors are in parallel.

Total Resistance = 1 / [(1/R1) + (1/R2) + (1/R3 + ....) ].

Firstly calculate the equation resistance then current through circuit by ohms law, then finally we can calculate power by p=vi or by p=i^2/r.

1/R = 199/120.
R = 120/199 = 0.6030150754 Kohm.
= 603.01 ohm.
It is approximately equal to 603 ohm.
P = VI = V*V/R.
= 48*48/603.
= 3.820895.

Current through 1000 Ohms = 48/1000 = 0.048.
Current through 3000 Ohms = 48/3000 = 0.016.
Current through 5000 Ohms = 48/5000 = 0.0096.
Current through 8000 Ohms = 48/8000 = 0.0796.
Total Current is 0.0796 mA Therefore power dissipated is 0.0796 mA*48V = 3.8208.
Current through 3000 Ohms = 48/3000 = 0.016.
Current through 5000 Ohms = 48/5000 = 0.0096.
Current through 8000 Ohms = 48/8000 = 0.0796.
Total Current is 0.0796 mA Therefore power dissipated is 0.0796 mA*48V = 3.8208.
