In summary, according to Ohm's Law, the voltage in an ideal battery remains constant regardless of the circuit it is connected to. This means that in an open circuit, where there is no load on the battery, the voltage will be the same as in an ideal battery.

question: referencing ohm's law, why is the voltage in an ideal battery equal to that in an open circuit?

I know ohm's law, and I know that an ideal battery has the same voltage no matter what it's connected to, but what does that have to do with an open circuit?

Hi Mango12! ;)

A real battery loses some of its voltage in a closed circuit.
Putting a load on real battery has its effect.
However, even a real battery behaves like an ideal battery if there's no load on it - that is, if we have an open circuit.
 

FAQ: Why is the voltage in an ideal battery equal to that in an open circuit?

What makes a battery "ideal"?

An ideal battery would have a high energy density, meaning it can store a large amount of energy in a small space. It would also have a long lifespan, be able to charge and discharge quickly, and have a low self-discharge rate.

Can an ideal battery be recharged indefinitely?

No, even the most advanced batteries have a limited number of charge cycles. However, an ideal battery would have a high number of charge cycles before significant degradation occurs.

How does temperature affect an ideal battery's performance?

Extreme temperatures, both hot and cold, can negatively impact a battery's performance. An ideal battery would operate efficiently in a wide range of temperatures and have built-in thermal management systems to regulate its temperature.

Is there a specific type of battery that is considered ideal?

The definition of an ideal battery can vary depending on the intended use. For consumer electronics, lithium-ion batteries are often considered ideal due to their high energy density and rechargeability. However, for larger applications such as electric vehicles, other battery chemistries may be more suitable.

Are there any downsides to using an ideal battery?

While an ideal battery would have many desirable qualities, it may also come with a higher cost and require more advanced technology to produce. Additionally, the production and disposal of batteries can have environmental impacts that need to be considered.
