4.2: Resistance and Ohm''s Law
This equation, which defines resistance, appears at first glance to say that the current through a resistor is proportional to the potential difference across it, and this is Ohm''s Law. Equation ref{4.2.1}, however, implies a simple proportionality between (V) and (I)only if (R) is constant and independent of (I) or of (V).

Ohms Law
As many readers already know, this is "Ohm''s law." The current is driven forward by the voltage. The "ampere" unit is the same thing as "coulombs per second," where one coulomb is 6 × 10 18 electrons, so it is a quantity of charge moving per unit of time, or a flow rate many ways equation 2.2 is analogous to equation 2.1 fact, if the reader ever has trouble remembering
Why are voltage and current inversely proportional to

6 FAQs about [Current proportionality factor battery]
What is battery capacity & Peukert exponent?
Battery capacity and Peukert exponent Battery capacity is expressed in Amp hour (Ah) and indicates how much current a battery can supply over time. For example, if a 100Ah battery is being discharged with a constant current of 5A, the battery will be totally discharged in 20 hours.
What is a rated battery capacity?
Manufacturers specify the capacity of a battery at a specified discharge rate. For example, a battery might be rated at 100 A·h when discharged at a rate that will fully discharge the battery in 20 hours (at 5 amperes for this example). If discharged at a faster rate the delivered capacity is less.
What is battery capacity?
Battery capacity is expressed in Amp hour (Ah) and indicates how much current a battery can supply over time. For example, if a 100Ah battery is being discharged with a constant current of 5A, the battery will be totally discharged in 20 hours. The rate at which a battery is being discharged is expressed as the C rating.
What are the parameters required for optimal battery charging?
The optimal charging algorithms require two parameters: maximum acceptable terminal voltage of the battery and the maximum current during charge. As observed by other researchers as well , these two parameters affect the life of the battery.
What is a good Peukert exponent for a lead acid battery?
An ideal (theoretical) battery has a Peukert exponent of 1.00 and has a fixed capacity regardless of the size of the discharge current. The default setting in the battery monitor for the Peukert exponent is 1.25. This is an acceptable average value for most lead acid batteries. Peukert’s equation is stated below:
What is the Peukert exponent of a battery monitor?
In the battery monitor the Peukert exponent can be adjusted from 1.00 to 1.50. The higher the Peukert exponent the faster the effective capacity ‘shrinks’ with increasing discharge rate. An ideal (theoretical) battery has a Peukert exponent of 1.00 and has a fixed capacity regardless of the size of the discharge current.
