In summary, when a key in a circuit is open, no current flows through the circuit. This is because an open circuit creates a break in the electrical path, preventing the movement of electrons. Consequently, devices connected to the circuit will not function until the key is closed, allowing...

When an electric current flows in an external magnetic field, it experiences a magnetic force, as in electric motors. The heat loss, or energy dissipated, by electric current in a conductor is proportional to the square of the current. A common unit of electric current is the ampere, which...
