Problem 12-14 Ohm's law - Part 2 - A

Diagram of circuit with current of 2.38 A

In the circuit above the current is 2.38A.­ What are

(a) the resistance R?
(b) the direction of the current through the resistor?
(c) the potential difference VAVC?

[Ans. (a) 1.36Ω   (b) toward top of diagram   (c) 3.24V]


Accumulated Solution

VR=3.24VR=ΔV/I=(3.24V)/(2.38A)=1.63Ω


Correct!
 
Which point in the figure is at a higher potential?

(A)

(B)
