Question

If wattage increases what will happen to bulb resistnace

Answer 1

Heya friend!!
Rajdeep here...

Watt measures the physical quantity of Power.
Relation between Power, resistance and Voltage is:
P = $V^{2}/R$
Where P is the Power, V is the Voltage and R is the Resistance.

Hence, R = $V^{2}/P$
So, if the Power (wattage) of the bulb increases, keeping the VOltage constant, the resistance decreases, so that the bulb glows more brightly.

Hope my answer is satisfactory...
Thanks!

Answer 2

Explanation:

Watt measures the physical quantity of Power.

Relation between Power, resistance and Voltage is:

P =  

Where P is the Power, V is the Voltage and R is the Resistance.

Hence, R =  

So, if the Power (wattage) of the bulb increases, keeping the VOltage constant, the resistance decreases, so that the bulb glows more brightly.

Hope my answer is satisfactory...

Thanks!
