Answer:
Input impedance of this transformer is 50 ohms.
Explanation:
Given that,
Number of turns in the primary coil,
Number of turns in the secondary coil,
Output impedance of the transformer,
The number of turns and the impedance ratio in the step down transformer is given by :
So, the input impedance of this transformer is 50 ohms. Hence, this is the required solution.
Answer : The average power delivered to the circuit is, 42.6 watt
Explanation :
The relation between power, voltage and current is:
where,
P = power of circuit = ?
I = current = 6.0 A
V = voltage = 7.1 V
Now put all the given values in the above formula, we get the average power delivered to the circuit.
Thus, the average power delivered to the circuit is, 42.6 watt
