An electric field of magnitude 3.50 kN/C is applied, embarking us on an electrifying journey into the realm of electric fields. Electric field strength, a fundamental concept in electromagnetism, plays a crucial role in shaping the behavior of electric charges and finds diverse applications in our everyday lives.
An electric field of magnitude 3.50 kN/C is applied to a certain material, causing its electric polarization to be 0.250 µC/m2. Just like a manufacturer uses electrical fuses in an electronic system to protect against excessive current, this electric field causes a displacement current whose magnitude is 0.875 mA/m2.
The material is thus a linear dielectric with a relative permittivity of 3.50.
This electric field, with its strength of 3.50 kN/C, provides a tangible representation of the invisible forces that govern the interactions between charged particles. It invites us to delve into the intricacies of electric fields, exploring their direction, effects on charges, and practical applications.
With an electric field of magnitude 3.50 kN/C applied, an electric air heater consists of a horizontal array of closely spaced parallel wires that carry current in the same direction. This design creates a uniform electric field between the wires, which heats the air as it passes through the heater.
Electric Field Strength
Electric field strength, denoted by E, is a measure of the strength of an electric field at a given point in space. It is defined as the force experienced by a positive test charge placed at that point, divided by the magnitude of the charge.
An electric field of magnitude 3.50 kN/C is applied to a region of space. This field can be used to create an electric potential difference, which can be used to power devices such as light bulbs. For example, adding a light switch to an electrical outlet involves creating a circuit that allows electricity to flow through the switch and to the light bulb.
The electric field of magnitude 3.50 kN/C provides the necessary potential difference to power the light bulb.
The SI unit of electric field strength is volts per meter (V/m).Typical electric field strengths found in everyday life include:
- Near a charged object: Thousands of volts per meter
- In the atmosphere during a thunderstorm: Hundreds of volts per meter
- Near a power line: Tens of volts per meter
Electric Field Direction: An Electric Field Of Magnitude 3.50 Kn/c Is Applied
The direction of an electric field is the direction in which a positive test charge would experience a force. Electric field lines are used to represent the direction of an electric field. These lines are drawn so that the tangent to the line at any point gives the direction of the electric field at that point.Electric
When an electric field of magnitude 3.50 kN/C is applied, the filament in an electric bulb glows because it’s made of a material like tungsten that has a high resistance. The resistance causes the filament to heat up, emitting light.
field lines can be used to visualize the direction of an electric field around charged objects. For example, the electric field lines around a positive charge point radially outward, while the electric field lines around a negative charge point radially inward.
Electric Field Effects on Charges
An electric field can exert a force on a charged object. The force experienced by a positive charge is in the direction of the electric field, while the force experienced by a negative charge is in the opposite direction.Electric fields can be used to accelerate charges.
An electric field of magnitude 3.50 kN/C is applied to a conductor. The current density in the conductor is proportional to the electric field. An ammeter is an electrical instrument used to measure the current flowing through a conductor. Thus, the current density in the conductor can be determined by measuring the current flowing through the conductor using an ammeter.
For example, in a particle accelerator, charged particles are accelerated by passing them through an electric field.
An electric field of magnitude 3.50 kN/C is applied to a guitar string, causing it to vibrate. This vibration can be adjusted by adjusting a truss rod on an electric guitar , which changes the tension of the string and thus its frequency.
