It is directly proportional to the number of turns of the coil and inversely proportional to the diameter of the coil.
For small deflections, however, the change of flux can be taken as directly proportional to the observed deflection.
The coil, therefore, takes a definite part of the whole current, and the force moving it and its pointer away from the zero position is directly proportional to the whole current.
It has been shown by direct experiment that the velocities are directly proportional to the electric force.
Now this velocity is inversely proportional to the pressure, so that the reaction should on this view be directly proportional to the pressure.
The fall of potential at the cathode is proportional to the square of the current, while the fall in the rest of the circuit is directly proportional to the current.
It is directly proportional to the square of the height for beams of the same length and breadth, instead of as the cube of this dimension as in stiffness.
Carefully conducted experiments upon the elasticity of bodies have shown that the changes in shape are directly proportional to the forces applied, provided that the limit of elasticity is not reached.
The cross-sectional areas of the two pistons are, on the other hand, directly proportional to the forces exerted by them.
Every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Since this reasoning will hold good for a comparison of forces at any two depths, we have the law: "The pressure exerted by a liquid is directly proportional to the depth.
But the number of atoms in any stratum is the measure of the force which emitted that stratum--that is to say, is directly proportional with the force.
The power of water is directly proportional to head, just as it is directly proportional to quantity.
The magnitude of the transmission process is directly proportional to this velocity, and is, therefore, also a function of the kinetic energy.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "directly proportional" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
