Electrostatic Precipitators: High-voltage electrodes ionize industrial smoke particles; charged particles migrate to grounded collection plates. Directly applies E field inside a conductor and charge migration under Coulomb force. Used in thermal power plants to reduce particulate emissions.

Photocopiers and Laser Printers: A photoconductor drum is uniformly charged. Laser light selectively discharges regions to form a latent charge image. Toner (oppositely charged powder) adheres to charged areas by Coulomb attraction, then transfers to paper. The entire process is an application of charge induction and field-driven force.

Capacitors in Electronic Circuits: Capacitors appear in virtually every electronic device. Camera flashes store energy (U = ½$CV^{2}$) in large capacitors and release it in milliseconds. DRAM memory cells store a single bit as the presence or absence of charge on a tiny capacitor. Power supply smoothing uses parallel capacitor banks.

Van de Graaff Generator: Transfers charge by induction onto a hollow conducting sphere. Since the field inside a conductor is zero, charge always migrates to the outer surface, allowing unlimited accumulation. Used in particle accelerators and high-voltage research.

Lightning Rods: A pointed conductor concentrates surface charge density σ at its tip (E = σ/ε_{0} is very large at sharp points). This ionizes the surrounding air, creating a preferential conduction channel that safely directs lightning to ground.

Inkjet and Electrostatic Printing: Ink droplets are charged and deflected by controlled electric fields — analogous to a dipole experiencing force in a non-uniform field. Precise charge control allows nanometre-scale positioning on printed circuits.

MEMS Sensors (Accelerometers): Micro-electromechanical systems measure acceleration by detecting changes in capacitance (C = ε_{0}A/d) as tiny proof masses move, changing the plate separation d. Present in every smartphone and automobile airbag system.

Nerve Impulse Transmission: The resting potential of a cell membrane (~−70 mV) arises from ionic charge separation across a capacitor-like lipid bilayer. Action potentials propagate by sequential charge redistribution — Coulomb forces drive ion channels.
