The number of windings on the primary coil of a transformer

Physics
1 answer:
vladimir1956 [14]3 years ago
8 0

Answer:

I. Vs = 8.0 Volts.

II. Is = 4.5 Amperes.

Explanation:

<u>Given the following data;</u>

Np = 1.5Ns = \frac {N_{P}}{N_{S}} = 1.5  ..... equation 1

Ip = 3.0 A

Vp = 12 V

To find the voltage and current on the secondary coil;

I. For the voltage in the secondary coil (Vs), we would use the following formula;

\frac {V_{P}}{V_{S}} = \frac {N_{P}}{N_{S}}  ...... equation 2.

Substituting eqn 1 into eqn 2, we have;

\frac {V_{P}}{V_{S}} = 1.5

\frac {12}{V_{S}} = 1.5

Cross-multiplying, we have;

V_{S} * 1.5 = 12

V_{S} = \frac {12}{1.5}

<em>Vs = 8.0 V</em>

II. For the current in the secondary coil (Is), we would use the following formula;

\frac {I_{S}}{I_{P}} = \frac {N_{P}}{N_{S}}  .... equation 3

Substituting eqn 1 into eqn 3, we have;

\frac {I_{S}}{I_{P}} = 1.5

\frac {I_{S}}{3.0} = 1.5

Cross-multiplying, we have;

I_{S} = 1.5 * 3.0

<em>Is = 4.5 A</em>

An object with a velocity of
algol [13]

Answer:

v = 1.7 m/s

Explanation:

Given that,

Initial velocity of the object, u = 1 m/s

Acceleration of the object, a = 1 m/s²

We need to find the velocity of the object after moving 1 m. Let v be the velocity. Using third equation of kinematics to find it i.e.

v^2-u^2=2ad\\\\v^2=2ad+u^2\\\\v^2=2(1)(1)+1^2\\\\v=\sqrt3\\\\v=1.7\ m/s

So, the final velocity of the object is 1.7 m/s.

A runner runs 300 m at an average speed of 3.0 m/s. She then runs another 300m at an average
Kaylis [27]

Answer:

B. 4 m/s

Explanation:

v=d/t

Running for 300 m at 3 m/s takes 100 seconds and running at 300 m at 6 m/s takes 50 seconds. 100 s + 50 s = 150 s (total time). Total distance is 600 m, so 600 m/ 150 s = 4 m/s.
