What about thermal inertia of resistor?
If current is fluctuating you will not get true instantaneous measurement of current. The settling time will depend on thermal inertia of resistor. AFAIK in induction heating applications where heating cycle is usually few seconds this thermal inertia of resistor makes the resistor method of measuring current unsuitable.
