Warm up set 7 Question (a) where a wire is connected to a battery 1.HRW6 28.TB.05. [119859] In the context of the loop and junctions rules for electrical circuits a junction is: (a) where a wire is connected to a battery (b) where three or more wires are joined (c) where a wire is bent (d) where a wire is connected to a resistor (e) where only two wires are joined

Question (a) the electric field (b) the electron drift velocity 2. HRW6 28.TB.18. [119872] Two wires made of the same material have the same length but different diameter. They are connected in parallel to one end of a battery. The quantity that is NOT the same for the wires is: (a) the electric field (b) the electron drift velocity (c) the current (d) the current density (e) the end-to-end potential difference

Question 3. HRW6 28.TB.26. [119880] The emf of a battery is equal to its terminal potential difference: (a) only when there is no current in the battery (b) only when a large current is in the battery (c) under all conditions (d) under no conditions (e) only when the battery is being charged
