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

In the circuit above the current is $2.38\; A$.­ What are

(a) the resistance $R$?
(b) the direction of the current through the resistor?
(c) the potential difference $V_A - V_C$?

[Ans. (a) $1.36\; \Omega$   (b) $\text{toward top of diagram}$   (c) $3.24\; V$]

Accumulated Solution

$V_R = 3.24\; V \\ R = \Delta V/I = (3.24 \;V)/(2.38\; A) = 1.63\; \Omega$

Correct!

Which point in the figure is at a higher potential?

(A)

(B)
