Question

if 0.2 ohm 0.3 ohm 0.4 ohm 0.5 ohm and 2 ohm resistors are connected to a 9 volt battery in parallel what will be the current through the 12 ohm resistor ​

Answer 1

• Resistance=R=12ohm
• Potential Difference=v=9v
• Current=I=?

Using ohms law

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

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

$\\ \sf\longmapsto I=\dfrac{9}{12}$

$\\ \sf\longmapsto I=0.7A$
