Question

when a potential difference of 1.4volt is applied across conductor the current flowing in it is 0.25A calculate the resistance​

Answer 1

Answer:

$\boxed{\mathfrak{Resistance \ (R) = 5.6 \ \Omega}}$

Given:

Potential difference (V) = 1.4 V

Current (I) = 0.25 A

To Find:

Resistance (R)

Explanation:

Formula:

$\boxed{ \bold{\sf R = \frac{V}{I}}}$

Substituting value of V & I in the equation:

$\sf \implies R = \frac{1.4}{0.25} \\ \\ \sf \implies R = \frac{1.4}{ \frac{1}{4} } \\ \\ \sf \implies R = 1.4 \times 4 \\ \\ \sf \implies R = 5.6 \: \Omega$

Answer 2

$\sf Potential ~Difference = 1.4~ V$

$\sf Current = 0.25 ~A$

$\boxed{\rm {Resistance = \frac{Potential \: Difference}{Current} }}$

$\sf Resistance = \frac{1.4~V}{0.25~A}$

$\sf{\red{ Resistance = 5.6 \: Ω}}$
