Current Electricity Charging Discharging Of Capacitors Question 559
Question: Three identical resistances A, B and C are connected as shown in the given figure. The heat produced will be maximum
[MP PMT 2004]
Options:
A) In B
B) In B and C
C) In A
D) Same for A, B and C
Show Answer
Answer:
Correct Answer: C
Solution:
Resistance of A is greater than the resistance of combination of B and C, hence voltage drop across A will be greater than that across B or C. Also $ H=\frac{V^{2}t}{R} $
Therefore $ H\propto V^{2} $ so $ H _{A}>(H _{B}=H _{C}) $ (R = constant)
