Question

Find the equivalent resistance in between A and B for the circuit shown in the figure.

• A. $30\Omega$
• B. $5\Omega$
• C. $10\Omega$
• D. $20\Omega$

Answer 1

The correct option is C $10\Omega$

The electric bulb has a filament called tungsten when electricity passes through this filament, it heats up and glows. This heat is generated due to the passage of electric current and the drift of electrons due to the current and the resistance it causes.
In this case, the bulb did not glow because, the current that was passed through the liquid was not sufficient to produce the heat required for the electric bulb to glow.
