Heya
V=IR
Ohm's Law tells us that the electrical current in a circuit can be calculated by dividing the voltage by the resistance.
In other words, the current is directly proportional to the voltage and inversely proportional to the resistance.
By ohm's law, resistance is inversely proportional to the current.
Greater the current, less is the resistance.
Among 1kw=1000w bulb and 100w bulb, 100w bulb has greater resistance.
Hope it helps
