Question

When a current of 0.2 A flows through a wire, a potential difference of 10 V is developed across its ends. What
is the electrical resistance of the wire?​

Answer 1

$\huge\mathfrak{Answer}$

$\huge\text{\underline{Given}}$

Current in wire = 0.2 Ampere

Potential Difference Across the end= 10 V

Resistance of wire = ?

For finding the electrical resistance of wire .We have to use ohm's relationship between Voltage, Current And Resistance.

$\bold\red{Ohms Law}$

According to Ohms law the potential difference applied across a conductor is directly proportional to the current flowing through it, If physical factors remains constant.

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

$\implies$ $\bold{R =\frac{10}{0.2} }$

$\implies$ $\bold{R = 50 Ohm}$

Hence, the Resistance of wire is 50 ohm.
