How many primary volts must be applied to a transformer with a turns ratio of 0.1 to obtain a secondary voltage of 9 V?
-
In a certain loaded transformer, the secondary voltage is one-fourth the primary voltage. The secondary current is
-
A certain transformer has a turns ratio of 1 and a 0.85 coefficient of coupling. When 2 V ac is applied to the primary, the secondary voltage is
-
The primary coil of a transformer is connected to a 60 V ac source. The secondary coil is connected to a 330
load. The turns ratio is 3:1. What is the secondary voltage? -
A certain amplifier has 600
internal resistance looking from its output. In order to provide maximum power to a 4 speaker, what turns ratio must be used in the coupling transformer? -
A transformer
-
The primary of a transformer is connected to a 6 V battery. The turns ratio is 1:3 and the secondary load, RL, is 100
. The voltage across the load is -
When a 200
load resistor is connected across the secondary winding of a transformer with a turns ratio of 4, the source "sees" a reflective load of
