Based on the information provided, the technician who is correct is: C. Both Technician A and Technician B.
<h3>What is an open circuit?</h3>
An open circuit can be defined as a type of electric circuit in which the continuity between the conducting wire (paths) has been broken or cut.
This ultimately implies that, an open circuit is designed and developed to prevent the flow of electric charges (electrons or currents) from one point in an electric circuit to another.
In Electrical engineering, a short usually causes an electric circuit protection device such as a fuse, circuit breaker, etc., to open when higher than normal current flows through the electrical circuit.

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:
A AND C
Explanation:
Two advantages of deforming steel at room temperature rather than at elevated temperatures are: (select 2 answers from the options below)
A. better dimensional accuracy to allow form complex parts with complex geometries.
C. a smoother surface finish to allow elimination of finish machining and grinding operations.
