Question

Three resistors 12 ohm, 18 ohm and 36 ohm are

connected in parallel. This parallel circuit is connected

in series with a resistor 'R'. The whole circuit is

connected to supply of 60 Volt and it is found that

power developed in 12 ohm resistor is 48 watts.

Determine the value of R and total power.​

Answer 1

Answer: the value of R is 9

power in R is 144

total power delivered by battery is 240
