Answer:

No.

Explanation:

The basic law to apply is the Ohm's law.
This law says that the voltage is equal to the product of the resistance and the current. In formula: #V=R*I#.
In your circuit you have a voltage of #33# V and a resistance of #6# #\Omega#. The current is then #33=6*I# #I=33/6=5.5# A.
In this circuit it will circulate 5.5 Amps of current, that will burn the fuse that can tollerate only 5 A.
