Igcse Model Questions Vol1 2017 Physics Question 11
Practice objective / multiple choice question 11 from the 2017 Igcse Model Questions Vol1 Physics examination.
Two identical copper wires A and B are made from the same material. Wire A has a resistance of \(4.0\ \Omega\) at \(20\ ^\circ\text{C}\) and \(5.2\ \Omega\) when its temperature is raised to \(100\ ^\circ\text{C}\). Wire B has a resistance of \(5.0\ \Omega\) at \(20\ ^\circ\text{C}\). When wire B is heated, its resistance becomes \(6.2\ \Omega\). Assuming the two wires have the same temperature coefficient of resistance, determine the temperature (in \(^\circ\text{C}\)) of wire B after heating.
