A 75 ohm light bulb and 150 ohm heater, what is
meant is the resistance in the bulb and the heater , the resistors are not necessary
a circuit element, see in real life it the electric device we use in our home ,
therefore do not get confused. Since they are connected in parallel , their
equivalent resistance will be given as
1/reff = 1/r1+1/r2
1/reff = 1/75+1/150
1/reff = 3/150
1/reff = 1/50
Reff = 50 ohm
