Is the RT 60 OHM?
Is the amperage through R2 6A?
How do I find the wattage R3 is operating at?
I know this is the basics of basics, please excuse my retardation.

Yes.
No. It's 2 Amps.

Power (Watts) is Voltage * Current.
Or Current^2 * Resistance.
Or Voltage ^2 / Resistance.

Use whichever one works.

60 Volts * 2 Amps = 120 Watts.
2 Amps ^ 2 * 30 Ohms = 120 Watts.
60 Volts ^ 2 / 30 Ohms = 120 Watts.

Ohm's law. Voltage = Current * Resistance. V = IR. That's pretty much the core of all circuit problems.

The Voltage of the circuit is 120 V.
To find the total resistance of resistors in series, just add them together. 10 + 20 + 30 = 60. The resistance of the circuit is 60 Ohms.

You know the Voltage. You know the resistance.

I = V/R, or 120/60.
