To solve the problem, we need to determine the temperature coefficient of resistance (α) of the conductor and then find the resistance at 0°C (R0). 1. Identify the given values: - Resistance at 20°C (R1) = 3.15 Ω - Re
A50Ωis connected to a battery of5V. A galvanometer of resistance100Ωis to be used as an ammeter to measure current through the resistance, for this a resistancersis connected to the galvanometer. Which of the following connections should be employed if the measu...
