Question

A resistor is placed in a circuit. The voltage of the circuit is changed and the current is measured. The graph seen here shows the data that was collected. Determine the resistance of the resistor in this circuit. A) 0.5 Ohms B) 1 Ohm C) 2 Ohms D) 3 Ohms

Answer 1

Answer:

C

Explanation:

I just took the test on usa test prep.

Answer 2

Answer:

The answer is C. 2 Ohms

Explanation:

The slope of this graph is the resistance within the circuit. Ohm's law states that V=IR. When this is solved for resistance, R =

V

I

. The slope in any graph is defined as the

change in Y

change in X

. Picking the first and last point, change in Y is voltage and change in X is current. m =

Y

X

=

12 V

6 A

= R = 2 Ohms.
