(1) There are three basic types of dc motors; series, shunt, and compound.
(2) In the series motor, the field windings, consisting of relatively few turns of heavy wire, are connected in series with the armature winding.
Regarding the above statements,
A) only No. 1 is true.
B) both No. 1 and No. 2 are true.
C) only No. 2 is true.

The correct option is C

Explanation:

No. 1 is not true because a Permanent magnet DC motor is also one of the main types of DC motors. A DC motor is any of a class of motors that converts direct current electrical energy into mechanical energy.

C) only No. 2 is true.

Explanation:

There are actually 4 main types of DC motors. Namely Series, Shunt, and Compound and Permanent Magnet DC Motors.

The permanent motor magnet requires a permanent magnet to generate flux of field. This form of DC motor offers excellent initial torque and strong speed control, however power is restricted so they are usually used in applications with low horsepower rates.

d they tend to lose electrons and become cations.

explanation:

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
