Question

Two cells of 1.25 V and 0.75 V are connected in series with anode of one connected to cathode of the other. The effective voltage will be ______.

विकल्प

• 0.75 V

• 1.25 V

• 0.50 V

• 2.0 V

Answer 1

Two cells of 1.25 V and 0.75 V are connected in series with anode of one connected to cathode of the other. The effective voltage will be 2.0 V.

Explanation:

The cells support each other.

E_eq = E₁ + E₂ = 1.25 + 0.75 = 2.0 V
