A battery with an internal resistance of 10.0 Ω produces anopen circuit voltage of 12.0 V. A variable load resistance with arange from 0 to 30.0 Ω is connected across the battery. (Note:A battery has a resistance that depends on the condition of itschemicals and that increases as the battery ages. This internalresistance can be represented in a simple circuit diagram asa resistor in series with the battery.) (a) Graph the power dissipatedin the load resistor as a function of the load resistance.(b) With your graph, demonstrate the following importanttheorem: The power delivered to a load is a maximum if the loadresistance equals the internal resistance of the source.
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
A battery with an internal resistance of 10.0 Ω produces an
open circuit voltage of 12.0 V. A variable load resistance with a
range from 0 to 30.0 Ω is connected across the battery. (Note:
A battery has a resistance that depends on the condition of its
chemicals and that increases as the battery ages. This internal
resistance can be represented in a simple circuit diagram as
a resistor in series with the battery.) (a) Graph the power dissipated
in the load resistor as a function of the load resistance.
(b) With your graph, demonstrate the following important
theorem: The power delivered to a load is a maximum if the load
resistance equals the internal resistance of the source.
