In the given problem, we are fixing a transformer for a toy truck that uses an 8 volt rms voltage.
00:12
So as this truck is using 8 volt rms voltage, hence we can say the voltage across the secondary coil of the transformer is 8 .0 volt.
00:28
And this is rms voltage.
00:30
The primary coil of the transformer is broken.
00:34
The secondary coil has 30 tons means ns is 30.
00:40
The primary coil is connected to 120 volt -wall outlet.
00:46
Means we can say voltage fed to the primary coil is 120 volt.
00:54
So, in the first part of the problem, we have to find the number of turns that should be in the primary coil.
01:05
To find it, we use a relation between the number of turns and the voltages across the coils, and that is the number of terms in the primary means the ratio of the number of turns in the primary to the secondary is exactly equal to the voltage fed to the primary and the voltage obtained across the secondary...
