How does an electric charge produce an electric field? How is this field maintained over time without the input of energy? When the charge moves, why is or isn't there any remnant of the field left behind in space?
The definition of the electric field ##E## doesn't contain energy. It's the force per Coulomb's charge has. That is, ##\vec{E}=\frac{\vec{F}}{q}.##Christina2987 said:How does an electric charge produce an electric field? How is this field maintained over time without the input of energy?
Yes, there is, for the speed of transition of the electric field is finite, which is the speed of light, ##c.##Christina2987 said:When the charge moves, why is or isn't there any remnant of the field left behind in space?

An electric field is a region in space where an electric charge experiences a force. It is created by electric charges and can be either positive or negative. The strength and direction of an electric field are measured in units of volts per meter (V/m).
While an electric field is the region where a charge experiences a force, the electric force is the actual force that acts on the charge. The electric field is a property of the space around an electric charge, while the electric force is the interaction between two charges.
Electric fields are created by electric charges. Positive charges create electric fields that point away from them, while negative charges create fields that point towards them. The strength of the electric field is directly proportional to the magnitude of the charge and inversely proportional to the distance from the charge.
Charged particles in an electric field will experience a force. If the particle is positively charged, it will move in the direction of the electric field, while a negatively charged particle will move in the opposite direction. The magnitude of the force on the particle is equal to the charge of the particle multiplied by the strength of the electric field.
Electric fields have various practical applications, such as in the functioning of electronic devices, power generation, and transmission. They are also used in medical equipment, such as MRI machines, and in particle accelerators. Electric fields also play a crucial role in the functioning of the human nervous system.
