GATE EE 1994

MCQ (Single Correct Answer)

-0.6

A d.c. potentiometer is designed to measure up to about $$2$$ $$V$$ with a slide wire of $$800$$ mm. A standard cell of emf $$1.18V$$ obtains balance at $$600$$ mm. A test cell is seen to obtain balance at $$680$$ mm. The emf of the test cell is

$$1.00V$$

$$1.34V$$

$$1.50V$$

$$1.70V$$
