How does a fused bulb differ from a normal bulb? Explain the diffference between a fused bulb and a normal bulb by drawing their sketches. What happens to the circuit when the bulb in it gets fused?

1>The  difference between the fused and the normal bulb is that the ciruit is breaked in the fused wire but in normal bulb it the circuit is not breaked .
2> in fused bulb there is no light but in normal bulb it gives the light
below the figure given of fused and normal bulb which describe its circuit.
         
the above figure shows that normal bulb is connected to positive and negative terminal and circuit is completed and thus gives light  but in fused bulb circuit is breaked and no light is given by fused bulb
