1.	In the circuit diagram shown, the two resistance wires A and B are of same length and same material, but A is thicker than B. Which ammeter will indicate higher reading for current? Give reason.
Answer» resistance is inversely proportional to Area So in this CASE A is thicker and has more area compared to B hence A less lesser RESISTANCEAND V= IR so at CONSTANT V I is inversely proportional to R Hence A having LEAST resistance it has more current and higher ammeter READING Explanation:
