... (a) Torque exerted by electrostatic force on positive charge τ = R ×F = −aF sin θ = −qEa sin θ. Torque exerted by electrostatic force on negative charge τ = −qEa sin θ. The electrostatic forces result in a net torque τ = −2qEa sin θ. For small θ, sin ≈ θ, we have τ = −2qEaθ. Also, from analogy of Ne ...

Electric current
An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators.The particles that carry the charge in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom, and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.
