Question

when a battery of 12v is connected across an unknown resistor their is current of 2.0 mA calculate the value of the resistance​

Answer 1

${\huge{\underline{\underline{\bf{\blue{To\: Find:-}}}}}}$

• The Value of the Resistance.

${\huge{\underline{\underline{\bf{\blue{Given:-}}}}}}$

• V=12 V
• I=2.0 mA

${\huge{\underline{\underline{\bf{\blue{Formula\: Used:-}}}}}}$

• V= IR. [By Ohm's Law]

${\huge{\underline{\underline{\bf{\blue{Solution:-}}}}}}$

ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ғɪɴᴅ ᴛʜᴇ ʀᴇsɪsᴛᴀɴᴄᴇ.

Given: V=12V and I=2.0 mA

$\green\longrightarrow$ Let the resistance be R

$\green\longrightarrow$By Ohm's Law,

$\green\longrightarrow$V=IR

$\green\longrightarrow$ R=V/I

$\green\longrightarrow$ R=12/2.0

$\green\longrightarrow$R=6Ω

${\huge{\underline{\underline{\bf{\blue{Final\: Answer:-}}}}}}$

$\huge\red{\fbox{\rm{Resistance=6Ω}}}$

Answer 2

ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ғɪɴᴅ ᴛʜᴇ ʀᴇsɪsᴛᴀɴᴄᴇ.

Given: V=12V and I=2.0 mA

⟶ Let the resistance be R

⟶ By Ohm's Law,

⟶ V=IR

⟶ R=V/I

⟶ R=12/2.0

⟶ R=6Ω
