Question

Resistors of 1, 2, 3 ohm are connected in the form of a triangle. If a 1.5 volt cell of negligible internal resistance is connected across 3 ohm resistor, the current flowing through this resistance will be

• A. 0.25 amp
• B. 0.5 amp
• C. 1.0 amp
• D. 1.5 amp

Answer 1

Answer: (B)

0.5 amp

Answer 2

$i_{1} + i_{2} = \frac{1.5}{3/2} = 1amp$

$\frac{i_{1}}{i_{2}} = \frac{3}{3}$ ⇒ $i_{1} = i_{2}$ ∴ $i_{2} = 0.5A = i_{1}$
