An ideal transformer has 50 turns in its primary and 250 turns in its secondary. 12 V ac is connected to the primary. Find:
Power suppled to the secondary?
To find the power supplied to the secondary of an ideal transformer, we need to calculate the product of the voltage and current in the secondary coil.
However, in order to determine the secondary current, we need information about the primary current. Without this information, we cannot directly calculate the power supplied to the secondary.
But if we assume that the transformer is ideal and that there are no losses, we can use the turns ratio to find the voltage across the secondary coil. The turns ratio is given by the ratio of the number of turns in the primary coil to the number of turns in the secondary coil.
In this case, the turns ratio is 50/250, which simplifies to 1/5. Since 12 V AC is connected to the primary, the voltage across the secondary coil will be:
Voltage_secondary = Voltage_primary * turns_ratio
= 12 V * 1/5
= 2.4 V
Now that we have the secondary voltage, we can calculate the current flowing through the secondary coil using Ohm's Law. However, we need additional information, such as the load impedance or resistance connected to the secondary coil, to calculate the current accurately.
Without this information, we cannot directly determine the power supplied to the secondary. So, we need more details in order to provide a specific answer to your question.
N= 250/12
Power in an ideal transformer will be the same in the primary as secondary. Because current is not mentioned, it is not possible to answer.
