Question

iii) Arheostat is used
(A) to bring on a known change of
resistance in the circuit to alter the current
(B) to continuously change the resistance
in any arbitrary manner and there by alter
the current
(C) to make and break the circuit at any
instant
(D) neither to alter the resistance nor the
current​

Answer 1

Answer:

Option B Is correct
