(a) If four identical resistors are connected in parallel and the equivalent resistance is 1N. What will the equivalent resistance be when they are connected in series? (b) If an electrical applicance has a working power of 600W and is connected to an electric supply of 220V, what should the current passing through the electrical applicance be for it to operate normally?
