If the resistor is in series with the rest of the circuit then a is the correct answer. The voltage across the resistor in series with another resistor is
where R is the big resistor and r is the small one and V is the total voltage drop across both. This is called a voltage divider

Answer:
Ro = 133 [kg/m³]
Explanation:
In order to solve this problem, we must apply the definition of density, which is defined as the relationship between mass and volume.
where:
m = mass [kg]
V = volume [m³]
We will convert the units of length to meters and the mass to kilograms.
L = 15 [cm] = 0.15 [m]
t = 2 [mm] = 0.002 [m]
w = 10 [cm] = 0.1 [m]
Now we can find the volume.
And the mass m = 4 [gramm] = 0.004 [kg]
