A transformer has a primary voltage of 480 volts and a secondary voltage of 120 volts. If the primary windings have 700 turns, how many turns are in the secondary windings? (voltage and number of turns are directly proportional.)
Answers
Answer:
Let t = number of turns in the secondary windings
480/120 = 700/t
Solve for t and you will have your answer.
HINT: Cross-multiply and then divide to find t.
Explanation:
A transformer has a primary voltage of 480 volts and a secondary voltage of 120 volts. If the primary windings have 700 turns, how many turns are in the secondary windings? (Voltage and number of turns are directly proportional.)
V%5BS%5D%2FV%5BP%5D=N%5BS%5D%2FN%5BP%5D
120%2F480=N%5BS%5D%2F700
Cross multiply:
480N%5BS%5D=120%2A700
480N%5BS%5D=120%2A700
480N%5BS%5D=84000
N%5BS%5D=84000%2F480
N%5BS%5D=175
Answer:
According to the question, the number of turns in the secondary windings are 175.
Explanation:
What is a transformer ?
A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.
What is Voltage?
Voltage, also known as electric pressure, electric tension, or (electric) potential difference, is the difference in electric potential between two points. In a static electric field, it corresponds to the work needed per unit of charge to move a test charge between the two points. In the International System of Units, the derived unit for voltage is named volt.
Let t = number of turns in the secondary windings.480/120 = 700/t
Solve for t and you will have your answer.
HINT: Cross-multiply and then divide to find t.
t= (120*700)/480
=175
