WebOct 29, 2024 · 1) Remove the glass of the bulb and measure the resistance of the filament. 2) Then take a flame and heat up the filament. 3) Measure the resistance of the filament. The filament may not survive long, but maybe long enough to … WebMar 5, 2013 · Notice that if the cross-sectional area of the long bulb is smaller (the filament is thinner) than that of the round bulb, then the resistance of the round bulb will be smaller. Now, if both of these bulbs are in series with a battery , then Kirchoff's junction rule tells us that both bulbs have the same current I going through them. jaw coupling cad
