If the current in a circuit is 2 + j2 amps and the resistance is 3 - j2 ohms, what is the voltage?
a.) 10+j2 volts
b.) 10-j2 volts
c.) 2-j2volts
d.) 2 + j2volts

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512

what chart am i supposed to follow?

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
