What is the resistance in ohms of the computer-monitor combination when a desktop computer and monitor together draw about 1.2 A of current and they plug into a wall outlet that is 120 V?

The combination will have a resistance of 100ohms, and will drew 144watts. But, the wall outlet will usually be fluctuating from 115V to 135V, 120V is't only a "reference". I suggest you measure it a voltmeter before doing any calculation.
Then, you can use this formula (ohms law) to find the correct answer : R = V/I
In our case : R(ohms) = 120V / 1.2A R = 100ohms

A desktop computer and monitor together draw about 0.6 A of current They plug into a wall outlet that is 120 V What is the resistance in ohms of the computermonitor combination?
To find the resistance in a circuit, use the equation R = V/I, where R is the resistence in ohms, V is the voltage, and I is the current in amps. Therefore, your equation is R = 120/0.6. Therefore, the resistance is 200 ohms. Hope this helps

How do you find resistance in a parallel circuit?
resistance inparallel decrease in value proportionally two resistance can be calculated as R1XR2/SUM OF R1+R2. many values can be calculated as a fraction 1/r+1/r2+1/3 ....and take the total sum reciprocal

What is a Parallel Resistance?
Parallel resistance refers to 2 or more resistors where the input sides are connected together and the output sides are connected together. The formula to calculate it is the inverse of the total resistance of the circuit is equal to the sum of the inverses of the individual resistances. 1/R (total) = 1/R (1) + 1/R (2) + 1/R (3) + …
