Ampere-Second to Coulomb Converter

Simplifying Electrical Charge Measurements

When working with electrical systems, understanding and converting between different units of electrical charge is crucial. The Ampere-Second to Coulomb Converter is a valuable tool that helps engineers, students, and professionals easily convert between these two related units of measurement.

What is an Ampere-Second?

An ampere-second, often abbreviated as A⋅s, is a unit of electrical charge. It represents the amount of charge transferred by a steady current of one ampere flowing for one second. This unit is commonly used in electrical engineering and physics calculations.

What is a Coulomb?

A coulomb, denoted by the symbol C, is the SI unit of electrical charge. It is defined as the amount of charge transferred by a current of one ampere in one second. Interestingly, one coulomb is exactly equal to one ampere-second.

The Conversion Formula

The conversion between ampere-seconds and coulombs is straightforward:

1 ampere-second (A⋅s) = 1 coulomb (C)

This means that the numerical value remains the same when converting between these units. The conversion formula can be expressed as:

Charge in coulombs (C) = Charge in ampere-seconds (A⋅s)

Conversion Table

Here's a helpful conversion table for common values:

Ampere-Seconds (A⋅s)	Coulombs (C)
1	1
5	5
10	10
50	50
100	100
1000	1000

Practical Examples and Calculations

Let's explore some practical examples to illustrate the use of the Ampere-Second to Coulomb Converter:

Example 1: Battery Capacity

A small battery is rated at 2000 mAh (milliampere-hours). Calculate its capacity in coulombs.

Solution:

1. Convert mAh to Ah: 2000 mAh = 2 Ah
2. Convert hours to seconds: 1 hour = 3600 seconds
3. Calculate ampere-seconds: 2 A × 3600 s = 7200 A⋅s
4. Convert to coulombs: 7200 A⋅s = 7200 C

The battery has a capacity of 7200 coulombs.

Example 2: Electric Current Flow

An electric current of 5 amperes flows through a wire for 10 seconds. Calculate the total charge transferred.

Solution:

1. Use the formula: Charge (C) = Current (A) × Time (s)
2. Charge = 5 A × 10 s = 50 A⋅s
3. Convert to coulombs: 50 A⋅s = 50 C

The total charge transferred is 50 coulombs.

Example 3: Capacitor Charging

A capacitor is charged with a constant current of 0.5 amperes for 30 seconds. What is the total charge stored in the capacitor?

Solution:

1. Use the formula: Charge (C) = Current (A) × Time (s)
2. Charge = 0.5 A × 30 s = 15 A⋅s
3. Convert to coulombs: 15 A⋅s = 15 C

The capacitor stores a total charge of 15 coulombs.

Applications of Ampere-Second and Coulomb Measurements

Understanding and converting between ampere-seconds and coulombs is essential in various fields:
