Answer 1

$\sf{\huge{\underline{\pink{Given :-}}}}$

• Potential Difference = 24 V

• Current = 0.4A

$\sf{\huge{\underline{\red{To\:Find :-}}}}$

• Resistance of resistor

• Value of I when V is 6V

$\sf{\huge{\underline{\orange {Answer :-}}}}$

According to the question,

We have,

• V = 24 V

• I = 0.4A

Case I :-

Resistance of resistor

We know that,

[ V = I R ]

R = $\dfrac{V}{I}$

➝ $\dfrac{24}{0.4}$

➝ $\dfrac{24}{4/10}$

➝ $\dfrac{24 \times 10 }{4}$

➝ $\cancel{\dfrac{240 }{4}}$

➝ 60 Ω

The Resistance of resistor is 60 Ω .

Case II :-

Value of I when V is 6V

[ V = I R ]

The current through conductor when battery is 6V .

• V = 6V

• R = 60 Ω

I = $\dfrac{V}{R}$

➝ $\cancel{\dfrac{6}{60}}$

➝ $\dfrac{1}{10}$

➝ 0.1 A

Value of I when V is 6V is 0.1 A .
