Is a series circuit with 12.08V and a 150 Ohm Quarter-Watt resistor safe? Answered

I have a series circuit with 12.08V from a DC power source running through it. There is only one quarter-watt resistor at 150 Ohms. Is the circuit considered safe and why?

Without expanded information on the circuit, iIt sounds like the 150 ohm resistor is meant to be terminated by a similar effective resistance (either a real resistance or a component like an LED) (ie it acts as part of a voltage divider)

I can say nothing about its safety with the limited information on hand.

Power = V x V / R or 144 / 150 about 1 watt,

that is three times more then what you say the resistor has.....

Besides at age 0 you are too young to measure voltage to four places.

What is the load?

If its doing nothing its very safe, if you draw more current than the resistor's rated load, its going to melt.
