Lightning conductors are used to protect buildings from lightning strikes. Which of the following statements is/are true about lightning conductors? 1. Lightning conductors create a localized electric field at their sharp pointed tops, facilitating a safe discharge path. 2. Lightning conductors reduce the effect of the strike by uniformly distributing the charge over the surface of the building. 3. Lightning conductors safely conduct the entire electrical charge deep down into the earth. 4. Lightning conductors must be installed at a position taller than the highest point of the building. Select the correct answer using the codes given below:
