Answer:
V=4v
Explanation:
To perform this operation, we will refer to Ohm's Law. This Law relates the terms current, voltage and resistance.
The current intensity that passes through a circuit is directly proportional to the voltage or voltage of the circuit and inversely proportional to the resistance it presents.
[tex]I=\frac{v}{r}[/tex]
Where
I=Current
V= Voltage
R=Resistance.
So, in this case:
R=200 ohm
I= 2mA = 0.002 A
V= searched variable
[tex]V=r*I[/tex]
[tex]V=(200ohm)(0.002A)=4V[/tex]
