# Are amp-seconds the same as capacitance?

• jamba88
And that's not even a problem.In summary, amp-hours are a measure of a battery's available charge and when connecting batteries in series, the voltage doubles while maintaining the same capacity rating.

## Homework Statement

What is an amp hour? Are they saying that batteries in series maintain the same capacitance when they say amp-hours?

When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours).

None

## The Attempt at a Solution

None

Well, you know that ampères measure electrical current, right? So what do you get when you multiply electrical current by time?

Capacitance has nothing to do with it. (There are no capacitors involved in a battery)

Perhaps jamba meant capacity, not capacitance.

What is an amp hour?
An amp-hour is a measure of a battery's available charge, which can be thought of as its capacity.

What have you been told about batteries and amp-hours from your class lectures or textbook?

When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours).

None

Uh, technically you are supposed to attempt solving a homework problem before receiving help from us.

## 1. What is the definition of an amp-second?

An amp-second, also known as a coulomb, is a unit of electrical charge that measures the amount of electric charge transferred in one second by a steady current of one ampere.

## 2. What is the definition of capacitance?

Capacitance is a measure of an object's ability to store an electric charge. It is defined as the ratio of the electric charge on an object to the potential difference across the object.

## 3. Are amp-seconds and capacitance equivalent units?

No, amp-seconds and capacitance are not equivalent units. Amp-seconds measure electric charge, while capacitance is a property that describes the ability of an object to store charge.

## 4. How are amp-seconds and capacitance related?

Amp-seconds and capacitance are related by the equation Q = CV, where Q is the electric charge, C is the capacitance, and V is the potential difference. This equation shows that capacitance is directly proportional to amp-seconds.

## 5. Can amp-seconds be converted to capacitance?

No, amp-seconds cannot be converted to capacitance because they are measuring different properties. However, capacitance can be calculated using the equation Q = CV, where C is the unknown capacitance and Q and V are known values of electric charge and potential difference, respectively.
