If R1 < R2 < R3, and if these resistors are connected in parallel in a circuit, which one has the greatest voltage drop?
1 answer:
Since the resistors are in parallel, each one has the same voltage applied across their terminals.
The smaller the resistance of the resistor, the greater the current passing through it:
But since all resistors have the same voltage, the voltage drop is the same for all three resistors.

Explanation:
I have attached an illustration of a solid disk with the respective forces applied, as stated in this question.
Forces applied to the solid disk include:
Other parameters given include:
Mass of solid disk,
and radius of solid disk,
a.) The formula for determining torque (), is
Hence the net torque produced by the two forces is given as a summation of both forces:
b.) The angular acceleration of the disk can be found thus:
using the formula for the Moment of Inertia of a solid disk;
where = Mass of solid disk
and = radius of solid disk
We then relate the torque and angular acceleration () with the formula:
