Which has more resistance: 100W bulb or 60W bulb? - Toppr

WebNov 8, 2015 · Lamps are approximately resistive loads so they behave this way. The important thing to know is that an increase in voltage produces a proportional increase in current. So, your question a , if you increase the voltage to a resistive load by a factor of \$110\$, the current will also increase by a factor of \$110\$. WebThe 25 W lamp has a higher resistence. Because P = V 2/ R ans hence Power is inversely proportional to the resistence. So P= V 2 /R. if V is same for both. P∝1/R. Hence if the power is halved the resistence is doubled. Thus, ratio of resistence of 50W lamp to 25 W lamp is 1:2. Suggest Corrections.
