What can an electric source supply?

Answer: An electric source, such as a battery, generator, or any electrical power supply system, can provide energy in the form of electricity to power circuits and devices. More specifically, an electric source primarily supplies electric current, voltage, and energy to a system. Let’s break this down in detail:

Key Elements Supplied by an Electric Source:

1. Electrical Energy (measured in Joules):

An electric source provides energy that can be converted into various forms, such as light, heat, sound, or mechanical energy, depending on the device it powers. Electrical energy is supplied by moving charges in a circuit.

The relationship between energy, charge, and voltage is given by:

E = Q \cdot V

Where:

  • E is the electrical energy (in joules),
  • Q is the charge (in coulombs),
  • V is the voltage (in volts).

For example, if the electric source supplies a charge of 500 coulombs and operates at a voltage of 12 volts, the total energy delivered would be:

E = 500 \, \text{Coulombs} \cdot 12 \, \text{Volts} = 6000 \, \text{Joules}.

2. Charge (measured in Coulombs):

An electric source can supply charge, which represents the flow of electrons through a circuit. The charge is moved via a potential difference (voltage), creating electric current. If your electric source supplies 500 coulombs of charge, it means that this amount of charge can flow through the circuit over time.

3. Electric Current (measured in Amperes):

The electric source generates current, which is the rate of flow of charge. This is given by:

I = \frac{Q}{t}

Where:

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

For instance, if a charge of 500 coulombs flows through a circuit in 10 seconds, the resulting electric current would be:

I = \frac{500 \, \text{Coulombs}}{10 \, \text{Seconds}} = 50 \, \text{Amperes}.

4. Voltage (measured in Volts):

Voltage, also known as electric potential difference, is the force that drives charges through a circuit. It is supplied by the electric source to power components such as resistors, capacitors, and other electronic devices. Voltage can be thought of as the “pressure” that pushes electrons.

5. Power (measured in Watts):

An electric source supplies power, which is the rate at which energy is delivered to a circuit or device. The formula for electrical power is:

P = I \cdot V

Where:

  • P is the power (in watts),
  • I is the current (in amperes),
  • V is the voltage (in volts).

If the electric source supplies 50 amperes of current at a voltage of 12 volts, the total power output would be:

P = 50 \, \text{Amperes} \cdot 12 \, \text{Volts} = 600 \, \text{Watts}.

6. Capacity:

The capacity of the electric source, such as a battery, is often specified in ampere-hours (Ah) or coulombs. For example:

  • A battery with a capacity of 500 coulombs implies it can provide a charge of 500 C over its lifetime at specified conditions.

How Does the Information Relate to LectureNotes’ Example?

When LectureNotes says an electric source can supply 500 coulombs, it simply means the total quantity of charge available for the circuit. If the specific voltage and time span are known, additional calculations can give:

  • Energy delivered,
  • Current over time,
  • Power supplied.

The key takeaway is that an electric source provides charge, voltage, energy, and power, which are fundamental to electrical systems.
