Resistors of 2Ω, 3Ω and 6Ω are available—one of each.
(a) Arrange the three resistors so that their equivalent resistance is exactly 4Ω. State clearly which resistors are in series and which are in parallel.
(b) Calculate the equivalent resistance of your arrangement to show that it is indeed 4Ω.
(c) If the network you designed in part (a) is connected to a 12V battery, calculate the current supplied by the battery.
