How is the Electric Field Strength Calculated?

The electric field strength indicates how strongly an electric field acts on a charged particle. In alternating electric fields, which constantly change due to alternating voltages, the field strength is calculated similarly to static fields but with consideration of frequency. The calculation follows the formula: E = U / d, where "E" is the electric field strength in volts per meter (V/m), "U" is the applied voltage in volts, and "d" is the distance between the charged objects in meters. In alternating fields, the voltage continuously varies, meaning that the field strength also fluctuates over time. To perform precise measurements or calculations, frequency, amplitude, and phase shift of the field should be considered.

What Are Alternating Electric and Magnetic Fields?

Alternating electric and magnetic fields arise from changing electric currents and voltages. An alternating electric field is generated by an alternating voltage, while an alternating magnetic field is created by a varying current flow. Both fields are closely connected and form electromagnetic fields, which are commonly found in household appliances or power lines. Alternating electric fields influence charged particles, while alternating magnetic fields act on moving charges, such as electric currents. These fields are not only relevant in technology but also in the environment and can have health effects depending on their intensity.
