Question

there are 48 cells of emf 2 volt and internal resistance 1 ohm. they are grouped in mixed grouping.if there combination a maximum current through a resistance of 12 ohm​

Answer 1

Answer:-

Finding Equivalent Potential difference

• V=48×2=96Volts
• Resistance=R=12ohm
• Maximum Current=I_max=?

According to ohms law

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

$\\ \sf\longmapsto I_{max}=\dfrac{V}{R}$

$\\ \sf\longmapsto I_{max}=\dfrac{96}{12}$

$\\ \sf\longmapsto I_{max}=8A$
