An Electric Source Supplying a Charge of 500 Coulombs

Answer: When talking about an electric source that can supply a charge of 500 Coulombs, it’s important to delve into a few key concepts related to electricity and circuits. Understanding charge, current, potential difference (voltage), power, and energy will give a comprehensive view of what it means for an electric source to supply such a charge.

Understanding Electric Charge

Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. The SI unit of electric charge is the Coulomb (C). One Coulomb is equivalent to the charge of approximately 6.242 x 10^{18} electrons. In practical terms, it describes the amount of electricity conveyed by an electric current of one ampere flowing for one second.

What is Current?

Current is the rate of flow of electric charge. It is measured in amperes (A). One ampere is equivalent to one Coulomb flowing through a point in a circuit per second. The relationship between charge (Q) and current (I) can be defined using the equation:

Q = I \times t

where ( Q ) is the charge in coulombs, ( I ) is the current in amperes, and ( t ) is the time in seconds.

Potential Difference and Voltage

The potential difference, commonly referred to as voltage (V), is the work done to move a charge from one point to another in an electric field. The unit of voltage is the Volt (V), defined as one Joule of energy per Coulomb of charge:

V = \frac{W}{Q}

where ( W ) is work in joules and ( Q ) is charge in coulombs.

Power and Energy in Electric Circuits

Power (P) in an electric circuit is the rate at which energy is used or transferred. It’s measured in watts (W), where one watt equals one joule per second. Power can be calculated using the formula:

P = V \times I

Energy consumed by an electrical device over a period of time is given by:

E = P \times t

where ( E ) is energy in joules.

Practical Implications of a 500 Coulomb Charge

An electric source capable of supplying 500 Coulombs may have different applications depending on the context:

1. Powering Devices:

  • If this supply is continuous, it can determine the operation period of a device. For instance, if a device draws a current of 10 amperes, the time it can operate with 500 Coulombs of charge is:
t = \frac{Q}{I} = \frac{500\, C}{10\, A} = 50\, \text{seconds}

2. Energy Storage:

  • In a rechargeable battery scenario, the charge represents the battery’s capacity. While the charge alone doesn’t specify voltage or total energy, high Coulomb capacity indicates more storage potential.

Real-World Applications

  1. Batteries: Many batteries store and supply a specific charge to power devices. The Ampere-hour (Ah) rating in batteries shows how many amperes the battery can supply over time. For example, a 1 Ah battery can supply 1 ampere for 3600 seconds (1 hour), equating to 3600 Coulombs.

  2. Capacitors: Capacitors store electrical charge and release it when needed. A capacitor with a significant charge rating, like 500 Coulombs, could discharge rapidly to perform a high-energy task.

Conclusion:

In summary, understanding an electric source’s capacity to supply 500 Coulombs involves examining how much charge can flow, by what means (current), and the force (voltage) driving it. These concepts are crucial for designing circuits, power systems, and energy storage solutions. If you need further clarification or have an application scenario in mind, feel free to ask!
