Question

The p. d across 3 resistor is 6 v. The current in the resistor will be

Answer 1

Answer:

v=6V

r=3ohm

v=i×r

i=v/r=6/3=2A

Answer 2

Question:

The potential difference across 3 Ω resistor is 6 V. The current in the resistor will be?

Answer:

$\bigstar{\bold{Current(I)=\:2\:A}}$

Explanation:

$\Large{\underline{\underline{\bf{Given:}}}}$

• Potential difference (V) = 6 V
• Resistance(R) = 3 Ω

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

• Current (I)

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ By Ohm's law current in a resistor is given by the equation

  I =V/R

→ Substituting the given datas, we get

  I = 6/3

$\boxed{\bold{Current(I)\:=\:2\:A}}$

$\Large{\underline{\underline{\bf{Notes:}}}}$

→ Ohm's law state that the current flowing through a conductor is directly proportional to potential difference applied across its ends provided the temperature and other physical conditions remain unchanged.

V = RI

→ The SI unit of current is Ampere (A).
