Question

Find the resistance of conductor if current flowing
through it is 500mA
Potential Difference
accross the ends of conductor is 10
volts​

Answer 1

Answer:

Given :-

Current (I) = 500 mA

Potential difference (V) = 10 V

To Find :-

The Resistance of the conductor

Solution :-

Step 1

$\sf\leadsto 1 \ mA = 10^{-3} \ A$

$\sf\leadsto 5 \ mA = 500 \times 10^{-3}$

$\sf\leadsto 5mA = 5\times 10^2\times 10^{-3}$

$\sf\leadsto I = 0.5 \ A$

Step 2

As per the Ohm's Law

$\sf\boxed{\sf V=IR}$

Substituting the values,

$\sf\dashrightarrow 10 = 0.5\times R$

$\sf\dashrightarrow \dfrac{10}{0.5} = R$

$\sf\dashrightarrow R = \dfrac{100}{5}$

$\sf\red{Resistance = 20\Omega}$

ANSWER

Resistance of conductor , R =20 ohm

Facts Related To Question:

Ohms Law:

• The law was developed by Georg Simon Ohm.

• This law gives the relation between current and potential difference.

• This law defines the term RESISTANCE

• The law states that "Current flowing through the conductor is directly proportional to the potential difference across the two ends of the conductor"
