Problem 12-14 Ohm's law - C

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

$V_R = 3.24\; V$

Correct!

The resistance is given by:

(A)    $R = \Delta V/I$

(B)    $R = \Delta V I$

(C)    $R = I/ \Delta V$
