Question

erence, current and resistivity, .
2. A resistance of 200 has a current of 2amp following in it. What p.d is there between its
ends?
​

Answer 1

Answer:-

• Resistance=R=200ohm
• Current=I=2A
• Potential Difference =V=?

We know that

$\boxed{\sf V=IR}$

$\\ \sf\longmapsto V=200\times 2$

$\\ \sf\longmapsto V=400V$

Note:-

SI unit of potential difference is Volts (V)
