Question

The accumulator has a …………………………so that the potential drop across the potentiometer wire remains steady. * a. Oscillating e.m.f b. Constant e.m.f. c. Oscillating current d. High resistance​

Answer 1

Answer:

The accumulator has a …………………………so that the potential drop across the potentiometer wire remains steady. * a. Oscillating e.m.f b. Constant e.m.f. c. Oscillating current d. High resistance

Explanation:

the answer is

option b

mark me a brilliant please

Answer 2

Answer:

Constant electromagnetic force

Explanation:

As the potential gradient remains a constant unit as long as the potential difference across the potentiometer wire remains constant.

So, the accumulator has a constant e.m.f so that the potential drop across the potentiometer wire remains steady.

(b) Constant e.m.f
