Question

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

Answer 1

Given:

The resistance of the bulb is,

`R=15.0\text{ }\Omega`

The voltage of the battery is

`V=12\text{ V}`

To find:

The current through the bulb

Step-by-step explanation:

The current through the bulb is,

`\begin{gathered} i=(V)/(R) \\ =(12)/(15.0) \\ =0.80\text{ A} \end{gathered}`

Hence, the current through the bulb is 0.80 A.
