Question

Two resistors of 10 ohms and 20 ohms are connected in parallel. This parallel combination is connected in series with 30 ohms resistor. Whole circuit is connected across 250V supply. If 10 ohm resistor gets open circuited what is the total current drawn from the supply. *

Answer 1

Answer:

the answer of this question will be ...${(\frac{10*20}{10+20})+30}=36.67$ ohm

so current (I) =250/36.67=6.82 (appx.)
