Anyone have a clue on how to solve for the X's?????
2.
first let us find the equivalent resistance of the 3 resistors:
Rt = (1/15 + 1/15 + 1/15)^-1 = 5 ohm
now using ohms law we know that:
x / Rt = 2.5 ---> x = 12.5 [v]
3.
again using the same strategy, we first find the equivalent resistance of the circuit:
Rt = 5 + x/2
now using ohms law we know that:
24 / (5+x/2) = 1.5
<=> 16 = 5+x/2
<=> x = 22 [ohm]
