A wire of resistance 0.1 ohm cm –1 bent to form a square ABCD of side 10 cm. A similar wire is connected between the corners B and D to form the diagonal BD. Find the effective resistance of this combination between corners A and C. If a 2V battery of negligible internal resistance is connected across A and C calculate the total power dissipated
Text Solution
Verified by ExpertsThe correct answer is:
B
Resistance of one side, k = 0.1 × 10 = 1 Ω Ω
R eq = 1 Ω Ω , P = 
= 4 watt
