1.Determine the number of free electrons in a 1 cm³ of copper at room temperature. 2. A resistor of 3.6 ohms is connected in series with another of 4.56 ohms. What resistance must be placed across 3.6 ohms so that the total resistance of the circuit shall be 6 ohms? 3. A circuit consists of three resistors of 3 ohms, 4 ohms and 6 ohms in parallel and a fourth resistor of 4 ohms in series. A battery of e.m.f. 12 V and internal resistance (in series with the battery e.m.f.) 6 ohms is connected across the circuit. Find the total current in the circuit and terminal voltage across the battery.
