Dielectric absorption rate or ratio is a testing parameter used to determine the opposition to current flow through an insulating material sometimes expressed as insulation resistance in ohms or megohms. Testing the integrity of insulation involves measuring its resistance to current flow across or through it at specific voltage levels. A high level of resistance indicates that very little current is escaping through the insulation. Conversely, a low level of resistance indicates a significant amount of current may be leaking through and along the insulation.
Similar to capacitive current, absorption current starts out relatively high and then decreases over time. As the voltage increases, the absorption level in the insulation decreases. This gradual change reflects the potential energy stored in and around the insulation.
The dielectric absorption rate or ratio is the comparison of the leakage current or insulation resistance over a set time interval. The end reading divided by the initial reading yields a number which if less than 1.00 generally indicates faulty insulation.
Another test similar to the dielectric absorption test is the polarization index ratio. This test is performed in much the same manner except with a longer time interval.

What is The rate of absorption?
The rate of absorption refers to the frequency or magnitude that a given drug moves in the bloodstream. The absorption involves a number of phases.The rate at which something absorbs depends on a few things. Temperature can dramatically affect the rate of absorption for example.
Why overhead absorption rate is important?
In absorption costing, overhead absorption rate or blanket rate is key to spread all overheads on production of volume of product, because if we don't have the overhead absorption rate manufacturing overhead cannot be spread or there is no basis for allocation of overheads on manufactured units.

What is a blanket overhead absorption rate How will you differentiate between blanket overhead rate and other overhead absorption rate?
In Blanket Overhead Absorption Rate applied is the same however it may differ if a company follow Departmental method Or frther break - up method
What 4 factors affect the rate of absorption?
One factor that affects the rate of absorption is the molecule size. Particle size, lipid water solubility, and the degree of ionization are also three other factors that affect the rate of absorption.
What is a blanket overhead absorption rate?
Blanket overhead absorption rate is the rate used to allocate total overhead costs to number of produce units in traditional accounting system
What would happen if transpiration rate is greater than absorption rate?

What are the three overhead absorption rates?
As far as I know there is only an overhead absorption rate and a full absorption rate. The alternative being marginal costing. There are 3 methods of absorption costing. These being Activity, Time and Efficiency but I'm not sure what you are asking exactly.
What is an absorption cell?
An absorption cell is a container which allows light to pass through, used to store and study liquids and their optical absorption rate.
