If the charge on a capacitor is doubled, what happens to the electric field between the plates? (2022)
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy in an electric field.
Step 2: Know that the electric field (E) between the plates of a capacitor is related to the charge (Q) on the plates.
Step 3: Remember the relationship: Electric field (E) is directly proportional to the charge (Q). This means if you change the charge, the electric field changes in the same way.
Step 4: If the charge on the capacitor is doubled (Q becomes 2Q), the electric field will also double (E becomes 2E).
Step 5: Conclude that when the charge is doubled, the electric field between the plates also doubles.
Electric Field and Charge Relationship – The electric field (E) between the plates of a capacitor is directly proportional to the charge (Q) on the plates, described by the formula E = Q/(ε₀A), where ε₀ is the permittivity of free space and A is the area of the plates.
