Bar heater filaments. Two bars of an electric fire glow orange,casting reflections on a mirrored surface behind them. An electric fire works by passing an electric current through a wire filament which is wrapped around a bar. As the current flows it causes the filament to heat up. Electric fires often have a reflective surface placed behind the bars to direct the heat radiation in one direction | |
