A 15.0 Ω light bulb is connected to a 12 V battery. What is the current flowing through the light bulb?

Sagot :

Given:

The resistance of the bulb is,

[tex]R=15.0\text{ }\Omega[/tex]

The voltage of the battery is

[tex]V=12\text{ V}[/tex]

To find:

The current through the bulb

Explanation:

The current through the bulb is,

[tex]\begin{gathered} i=\frac{V}{R} \\ =\frac{12}{15.0} \\ =0.80\text{ A} \end{gathered}[/tex]

Hence, the current through the bulb is 0.80 A.
