Question

if a current of 3A flows through a resistance of 3ohm . calculate the potential difference across its ends

Answer 1

we know that according to ohm"s law
V=IR
V=3×3
V=9volt

SO POTENTIAL DIFFERENCE ACROSS ITS ENDS IS OF 9 VOLT

Answer 2

Answer:-

• Current=I=3A
• Resistance=R=3ohm
• Potential Difference=V=?

According to ohms law

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

$\\ \rm\longmapsto V=IR$

$\\ \rm\longmapsto V=3\times 3$

$\\ \rm\longmapsto V=9V$
