The force in the primary winding of the transformer 11a, the voltage across its rings is 9.8 V. What is the current in the secondary winding if the voltage across its rings is 220 V?
Initial data: I1 (current in the primary winding) = 11 A; U1 (voltage to the rings of the primary winding) = 9.8 V; U2 (voltage across the secondary winding rings) = 220 V.
The current strength in the secondary winding of the transformer is determined from the ratio: U1 / U2 ≈ I2 / I1, whence I2 = U1 * I1 / U2.
Calculation: I2 = 9.8 * 11/220 = 0.49 A.
Answer: The current in the secondary winding of the transformer is 0.49 A.
