document.write( "4 watts is the POWER of the bulb, which is the amount of energy per unit of time, in this case joules per second.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To calculate amount of energy consumed (or radiated) by the bulb, you should multiply the power in watts by the time in seconds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Notice that 1 watt multiplied by 1 second is 1 joule.\r\n" );
