Question

A current of 0.2 ampere flows through a conductor of resistance 4.5 ohm calculate

Answer 1

Answer:-

• Current=I=0.2A
• Resistance=R=4.5ohm
• Potential difference =V=?

According to ohms law

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

$\\ \sf\longmapsto V=IR$

$\\ \sf\longmapsto V=0.2\times 4.5$

$\\ \sf\longmapsto V=0.9V$
