Questions
For ensuring dissipation of same energy in all three resistors (R1, R2 and R3) connected as shown in figure, their values must be related as:
detailed solution
Correct option is C
If R2 = R3 and R2 = 4R1, thenNow, PR1 = V/32R1 = V29R1PR2 = 2V/324R1 = V29R1 and PR3 = 2V/324R1 = V29R1Talk to our academic expert!
