<h2>
Corrected Question:</h2>
A step-up transformer has 26 turns on the primary coil and 720 turns on the secondary coil. If this transformer is to produce an output of 4100 V with a 16-mA current, what input current and voltage are needed?
<h2>
Answer:</h2>
The input current and voltage needed are 443 mA and 148 V respectively.
<h2>
Explanation:</h2>
In a step-up transformer, the relationship between the number of turns in its primary coil (), the number of turns in its secondary coil (), the input voltage (), the output voltage (), the input current (), and the output current () is given by;
= =
This implies that;
= ---------------------(i)
= ---------------------(ii)
From the question;
= 26 turns
= 720 turns
= 4100V
= 16mA = 16 x 10⁻³A
(a) Substitute these values into equation (ii) as follows;
=
Solve for ;
= 720 x 16 x 10⁻³ / 26
= 443 x 10⁻³
= 443 mA
Therefore the input current needed is 443mA
(b) Also, substitute those values into equation (i) as follows;
=
Solve for ;
= 4100 x 26 / 720
= 148 V
Therefore, the input current needed is 148 V
Answer:
poisson's ratio
Explanation:
when a tenstile stress or comperresiv stress is applied ti a cylindrical or rod there is simultaneously axial and lateral strain within the elastic range . The ratio of lateral to the axial strain is called poisson's ratio . It has no unit , as it is the ratio of two strains
