An electric field is a physical field that surrounds a charged particle and exerts a force on other charged particles within its influence. It can be thought of as the space around a charged particle where the force of the particle's charge can be felt.
Capacitance is a measure of an object's ability to store electric charge. It is directly proportional to the strength of the electric field and inversely proportional to the distance between the charged objects. In other words, the stronger the electric field and the closer the charged objects, the higher the capacitance.
The equation for calculating electric field is E = F/q, where E is the electric field strength in Newtons per Coulomb (N/C), F is the force in Newtons (N), and q is the charge in Coulombs (C).
As distance between charged objects decreases, the electric field strength increases and the capacitance also increases. This is because the closer the objects are, the stronger the force of the electric field and the more charge can be stored between them.
Electric field and capacitance have many practical applications, such as in electronic devices like capacitors, which store electric charge. They are also important in the functioning of batteries, generators, and electric circuits. Additionally, understanding these concepts is crucial in fields such as electrical engineering, physics, and astronomy.
