The primary coil of a transformer is connected to a standard wall socket. A resistance R is connected across the secondary coil. The resistance across the secondary coil is increased. What happens to the current in the primary coil, and what happens to the power being supplied by the wall socket? The current in the primary coil decreases, and the power being supplied by the wall socket decreases. O The current in the primary coil decreases, and the power being supplied by the wall socket increases. O The current in the primary coil increases, and the power being supplied by the wall socket decreases. O The current in the primary coil decreases, but the power being supplied by the wall socket remains the same. O The current in the primary coil increases, and the power being supplied by the wall socket increases.
