two bulbs whose resistances are in ratio 1:2 are connected in parallel to a source of constant voltage what will be the ratio of power dissipated in the bulbs?

Expert Answer:

R1:R2 = 1:2
They are connected in parallel across source of voltage V.
Thus, the potential difference across each of them is V.
 
Now, the power dissipated across the resistor is P = V2/R
 
Thus, the ratio of power is:
