question_answer
Two electric bulbs whose resistances are in the ratio of 1 : 2 are connected in parallel to a constant voltage source. The powers dissipated in them have the ratio [NCERT 1977; MP PMT 1994, 2000]
A) 1 : 2
B) 1 : 1
C) 2 : 1
D) 1 : 4
Correct Answer:
C
Solution :
We know that \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{R}_{2}}}{{{R}_{1}}}=\frac{2}{1}\]
