A dc motor with its rotor and field coils connected in series has an internal resistance of 3.2 Ω. When running at full load on
pochemuha

Answer:

The current drawn by the motor from the line is 4.68 A.

Explanation:

Given that,

Internal resistance of the dc motor, r = 3.2 ohms

Voltage, V = 120 V

Emf in the motor, \epsilon=105\ V

We need to find the current drawn by the motor from the line. A dc motor with its rotor and field coils connected in series, applying loop rule we get :

V=\epsilon+Ir

I is current drawn by the motor

I=\dfrac{V-\epsilon}{r}\\\\I=\dfrac{120-105}{3.2}\\\\I=4.68\ A

So, the current drawn by the motor from the line is 4.68 A. Hence, this is the required solution.

If an object doubles in mass, what happens to its inertia?
son4ous [18]

Inertia is proportional to mass. It is a measure of the resistance to changes in velocity. Inertia is a property of mass and cannot change. Momentum changes as an object changes its velocity.


HENCE The inertia will also be doubled
