Power Dissipated in a Circuit: Problem Solving01:15

Power Dissipated in a Circuit: Problem Solving

1.6K
The equivalent resistance of a combination of resistors depends on their values and how they are connected.
The simplest combinations of resistors are series and parallel connections. In a series circuit, the first resistor's output current flows into the second resistor's input; therefore, each resistor's current is the same. Thus, the equivalent resistance is the algebraic sum of the resistances. The current through the circuit can be found from Ohm's law and is equal to the...

Determining Electric Field From Electric Potential01:12

Determining Electric Field From Electric Potential

4.9K
The electric field and electric potential are related to each other. If the electric field at various points in the region of interest is known, it can be used to calculate the electric potential difference between any two points. Similarly, if the electric potential is known for various points, then it is possible to calculate the electric field.
In general, regardless of whether the electric field is uniform, it points in the direction of decreasing potential because the force on a positive...

Finding Electric Potential From Electric Field

5.4K
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where calculating the electric field is more straightforward than finding the potential, the electric field is used to calculate the system's potential. For a positive charge, the electric field is radially outward, and the potential is positive at any finite distance from the positive charge. In such an electric field, the motion away from the...

ATP Driven Pumps I: An Overview01:27

ATP Driven Pumps I: An Overview

9.8K
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and...

Additional Subnuclear Structures02:10

Additional Subnuclear Structures

5.3K
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Dynamic Equilibrium02:20

Dynamic Equilibrium

62.0K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Area of Science:

  • Non-equilibrium thermodynamics
  • Complex systems
  • Soft matter physics

Background:

  • Physical systems open to energy flow can display spontaneous symmetry breaking and self-organization.
  • These phenomena lead to the formation of dissipative structures, which are key in understanding complex systems.
  • Electrically driven systems offer a unique platform to study these self-organizing behaviors.

Purpose of the Study:

  • To investigate the oscillatory mode of an electrically driven dissipative structure.
  • To explore the underlying electromagnetic mechanisms responsible for the observed spatio-temporal behaviors.
  • To validate a dynamical systems model against empirical observations and predict system behavior.

Main Methods:

  • Experimental setup using aluminum beads in oil subjected to high voltage.
  • Observation and analysis of self-organized 'tree' structures and their oscillatory movement.
  • Development and application of a dynamical systems model for electromagnetic phenomena.

Main Results:

  • The system self-organizes into conductive 'tree' structures exhibiting spatio-temporal oscillations.
  • The dynamical systems model successfully reproduces the observed oscillatory behavior.
  • Empirical results align with model predictions under varied constraints.

Conclusions:

  • The electrically driven dissipative structure exhibits complex oscillatory dynamics.
  • The system's behavior is consistent with a dynamical systems model of electromagnetic interactions.
  • There is a tendency for the system to favor states with maximum entropy production, supporting the Maximum Entropy Production Principle.
