What is the importance of superposition principle in electristatics?

Explain the superposition principle for static electric forces and write its general equation.

Obtain the resultant wave of more than two wave functions by representing the superposition principle mathematically.

In electrical circuit theory, a circuit C(t) called a linear circuit if it satisfies the superposition principle given by C(at_(1)+bt_(2))=aC(t_(1))+bC(t_(2)) , where a, b are constants. Show that the circuits C(t)=3t is linear.
