Question

The voltage between two points in a circuit is 4.2 V. If the resistance between

Answer 1

Answer:

A. 0.058 A

Explanation:

Answer 2

Answer:

I = 0.058 [A]

Explanation:

Ohm's law is defined as voltage equal to the product of current by resistance.

$V =I*R$

where:

V = voltage = 4.2 [V]

I = current [amp]

R = resistivity = 72 [ohm]

Now clearing I, we have:

$I = V/R\\I = 4.2/72\\I = 0.058 [A]$
