Question

If \( R_1, R_2, R_3, R_4, R_5 \) are resistances of each of five sections of starter of d.c. shunt motor, then these resistances are

• A. not in Geometric progression
• B. in Geometric progression
• C. in Arithmetic progression
• D. in Harmonic progression

Hint:

Starter resistors are designed based on practical performance, not mathematical progression.

Answer 1

The Correct Option is A

Starter resistances are chosen for smooth current control and not in any fixed progression like geometric or arithmetic.
