A circuit with a resistance of 6 Omega has a fuse melts at 5 A. Can a voltage of 33 V be applied to the circuit without blowing the fuse?

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.
