Electric Potential and Capacitance Problems

Front

What is the formula for calculating the equivalent capacitance (C_eq) of capacitors in series?

Front

What is the definition of electric potential (V)?

Back

Electric potential (V) is defined as the amount of electric potential energy per unit charge at a point in an electric field.

What is Coulomb's Law?

Front

How does doubling the charge of two point charges affect the electric force between them?

Back

If both charges are doubled, the electric force becomes four times greater, as it is directly proportional to the product of the charges.

Front

What happens to the electric force if the distance between two charges is tripled?

Back

If the distance is tripled, the electric force becomes one-ninth of the original force, as it is inversely proportional to the square of the distance.

Front

What is the principle of superposition in electrostatics?

Back

The principle of superposition states that the total electric force acting on a charge due to multiple other charges is the vector sum of the individual forces exerted by each charge.

What is the unit of capacitance?

Back

The unit of capacitance is the farad (F), which is defined as one coulomb per volt (C/V).
