Coulomb’s Law
- Formula: $F = k \frac{{q_1 \cdot q_2}}{{r^2}}$
- Explanation: Coulomb’s law gives the force of interaction between two charged objects.
Electric Field
- Formula: $E = \frac{{k \cdot q}}{{r^2}}$
- Explanation: Electric field is a region around a charged object where it exerts a force on other charged objects.
Electric Potential
- Formula: $V = \frac{{k \cdot q}}{{r}}$
- Explanation: Electric potential is the amount of electric potential energy per unit charge at a certain point.
Gauss’s Law
- Formula: $\Phi_E = \frac{{q_{enclosed}}}{{\epsilon_0}}$
- Explanation: Gauss’s law relates the electric flux through a closed surface to the charge enclosed within that surface.
Electric Potential Due to a Point Charge
- Formula: $V = \frac{{k \cdot q}}{{r}}$
- Explanation: The electric potential due to a point charge decreases as the distance from the charge increases.
Electric Potential Due to Multiple Point Charges
- Formula: $V_{total} = \sum{V_i}$
- Explanation: The total electric potential due to multiple point charges is the sum of the individual electric potentials.
Electric Potential Energy
- Formula: $PE = \frac{{k \cdot q_1 \cdot q_2}}{{r}}$
- Explanation: Electric potential energy is the energy associated with the position of charged objects.
Capacitance
- Formula: $C = \frac{{Q}}{{V}}$
- Explanation: Capacitance is the ability of a conductor to store electric charge.
Capacitors in Series
- Formula: $\frac{{1}}{{C_{\text{{total}}}}} = \frac{{1}}{{C_1}} + \frac{{1}}{{C_2}} + \ldots$
- Explanation: Capacitors in series have an equivalent capacitance that is the reciprocal of the sum of the reciprocals of the individual capacitances.
Capacitors in Parallel
- Formula: $C_{\text{{total}}} = C_1 + C_2 + \ldots$
- Explanation: Capacitors in parallel have an equivalent capacitance that is the sum of the individual capacitances.
