Question

an iron box is used in the electrical circuit having a voltage of 220 volt.if current of 2.5ampere flows through it.calculate the resistance of the iron box​

Answer 1

Answer:-

• Potential Difference=V=220V
• Current=I=2.5A.
• Resistance=R=?

According to ohms law

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

$\\ \rm\longmapsto Resistance=\dfrac{220}{2.5}$

$\\ \rm\longmapsto Resistance=88\Omega$

$\\ \qquad\underline{\boxed{\bf{\therefore Resistance=88Ω}}}$
