21.
For the two port of figure, z22 is
Answer: Option
Explanation:
22.
The internal impedance of a source is 3 + j 4 Ω. It is desired to supply maximum power to a resistive load. The load resistance should be
Answer: Option
Explanation:
RL = 32 + 42.
23.
In figure readings of the two voltmeters should be
Answer: Option
Explanation:
Both voltmeter connected in parallel, hence read same voltage as applied.
24.
The internal impedance of a source is 3 + j 7 Ω. For maximum power transfer, load impedance should be
Answer: Option
Explanation:
Load impedance should be conjugate of source impedance.
25.
In the circuit of figure, the current through battery E3 is
Answer: Option
Explanation:
4 A current is flowing into the battery. Therefore, it is charging current.
