Given an impedance of 0 + j 15 ohms, what type of load is this? capacitive purely capacitive inductive purely resistive purely inductive Given an impedance of 13ohms / - 90 degree, what type of load is this? purely capacitive purely resistive capacitive inductive purely inductive Given an impedance of 6ohms - 10 degree with a current of 4A 28 degree, what is the phase of the voltage? Given an impedance of 5ohms - 58 degree with a current of 4A - 50 degree, what is the magnitude of the voltage?

Explanation / Answer

5.
Ans E : Purely inductive
6.
Ans A: Purely capacitive
7.
phaseof voltage=phase of current+phase of impedence
=28-10
=18 degree
8.
Magnitude of voltage= I*R
    =4*5
=20 v
