Question

the potential difference across the conductor of 8 volt carries a current of 4A. calculate the resistance​

Answer 1

Given:

• Potential difference,V = 8 v

• Current, I = 4 A

To be calculated:

Calculate the resistance, R ?

Formula used :

V = I × R

Solution:

We have, potential difference and current.

V = I × R

★ Substituting the values in the above formula,we get

⇒ 8 = 4 × R

⇒ R = 8/4

⇒ R = 2 ohms

Extra information:

★ Electric current: Rate of flow of charge.

• It has magnitudes as well as direction.

• S.I unit of current = Ampere ( A )

• 1 A = 1 C / 1 S

• Instrument used to measure current levels is Ammeter.

The Potential Difference Across the Conductor of 8 Volt Carries a Current of 4A. Calculate the Resistance ..

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\implies\tt{Current(I)=4A}$

$\implies\tt{Potential\:Difference(V)=8v}$

$\implies\tt{Resistance(R)=?}$

➥Now ,

➥Using Formula : -

$\implies\tt{\small{\boxed{\bold{\bold{\red{\sf{V=I\times{R}}}}}}}}$

➥Putting Values : -

$\implies\tt{8=4\times{R}}$

$\implies\tt{\cancel\dfrac{8}{4}=R}$

$\red\longmapsto\:\large\underline{\boxed{\bf\green{R}\orange{=}\purple{2\:Ohms}}}$

☛So , The Resistance is 2 Ohms..

✔Electric Current : -

An Electric current is the rate of flow of charge which flows from negative point to positive point.It is denoted by symbol I .The SI unit of current is Ampere(A)..

Formula of Current is : -

$\leadsto\tt\bold{I =\dfrac{V}{R}}$
