A conductor or wire which carries electric charges. A circuit must be closed or complete. If circuits are open, the current cannot flow. These are the conditions that are necessary to make an electric current flow. The image below shows a current passing in a closed circuit. Current Flowing...
Each of two long straight parallel wires separated by a distance of 16cm carries a current of 20A in the same direction. What is the magnitude of the resulting magnetic field at a point that is 10cm from each wire? Observe th...
