Electric Field Intensity is a vector quantity that has both magnitude and direction. It depends on the amount of charge present on the test charge particle and is measured in volts per meter (V/m).
The calculator uses the formula:
Where:
Explanation: The formula calculates electric field intensity by dividing the drift velocity of dispersed particles by their electrophoretic mobility.
Details: Accurate calculation of electric field intensity is crucial for understanding particle behavior in electrophoretic processes, designing electrophoresis equipment, and analyzing charged particle movement in various scientific and industrial applications.
Tips: Enter drift velocity in m/s and electrophoretic mobility in m²/V·s. Both values must be positive numbers greater than zero.
Q1: What is electrophoretic mobility?
A: Electrophoretic mobility is defined as the ratio of electrophoretic (drift) velocity to the electric field strength at the location where the velocity is measured.
Q2: What factors affect electrophoretic mobility?
A: Electrophoretic mobility depends on the charge of the particle, the viscosity of the medium, and the size and shape of the particle.
Q3: What are typical units for electrophoretic mobility?
A: Electrophoretic mobility is typically measured in square meters per volt per second (m²/V·s).
Q4: Where is this calculation commonly used?
A: This calculation is commonly used in electrophoresis techniques, colloidal science, and various analytical chemistry applications involving charged particles.
Q5: How does temperature affect the calculation?
A: Temperature can affect both drift velocity and electrophoretic mobility through changes in viscosity and particle behavior, so measurements should be conducted under controlled temperature conditions.
