PhysicsEasysingle choice

Three cells of emf $1 V$ and internal resistance $1 Ω$ each are connected as shown. Effective emf of combination between the points $P$ and $Q$ is -

Options:

Answer:

Solution:

Two batteries of emf $1 V$ are combined, and two resistance also combine in series

$E_{n e t} = \frac{E_{1} r_{2} - E_{2} r_{1}}{r_{1} + r_{2}} = \frac{2 - 2}{2 + 1} = 0$
