A circuit with a resistance of #9 Omega# has a fuse melts at #6 A#. Can a voltage of #18 V# be applied to the circuit without blowing the fuse?

Answer:

Yes, its possible.

Explanation:

To answer, apply the resistance formula, and if #Current < 6#, it will work without melting:
#"Resistance" = "Voltage"/"Current"#
#9 Omega = (18 "V") /"Current"#
# "Current" = 18/9 = 2"A"#

So, it is possible, because the current will be #2"A"#.
