Question

The value of voltage in a circuit is 3v and the value of the current is 0.6m calculate its resistance?

Answer 1

Given:-

• Potential Difference ,V = 3v

• Current ,I = 0.6 A

To Find:-

• Resistance ,R

Solution:-

By using Ohm's Law

• V = IR

where,

V is the Potential Difference

I is the Current

R is the Resistance

Substitute the value we get

→ 3 = 0.6×R

→ R = 3×0.6

→ R = 1.8 Ω

Therefore,the Resistance is 1.8 ohms .

Additional Information !!!

•Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

• Potential difference = Work done /Charge.

• V = W/Q

here

V is the potential difference

W is the work done

Q is the charge

• SI unit of electric potential energy is volt (V).

• 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.

Answer 2

Answer:

Given :-

• The value of voltage in a circuit is 3v and the value of the current is 0.6 A.

To Find :-

• What is the resistance.

Formula Used :-

$\large\green{\underline{{\boxed{\textbf{V\: =\: IR\:}}}}}$

where,

• V = Potential difference
• I = Current
• R = Resistance (Ω)

Solution :-

Given :

• Potential difference (V) = 3v
• Current (I) = 0.6 A

According to the question by using the formula we get,

⇒ V = IR

⇒ 3 = 0.6 × R

⇒ R = 0.6 × 3

➠ R = 1.8 Ω

$\therefore$ The resistance of a circuit is 1.8 Ω .
