Question

a desktop computer and monitor together draw about 2 A of current they plug into a wall outlet that is 120 V what is the Resistance, in ohms, of the computer monitor combination

Answer 1

Answer:

$60 \Omega$

Explanation:

the relation between current, voltage and resistance in an electrical circuit is given by Ohm's law:

$V=IR$

where V is the voltage, I is the current and R is the resistance. In this problem, the current is I=2 A, the voltage is V=120 V, therefore we can arrange the previous equation and find the resistance:

$R=\frac{V}{I}=\frac{120 V}{2 A}=60 \Omega$
