When two resistors are in parallel combi...

When two resistors are in parallel combination then determine `i_(1)" and " i_(2)` if the combination carries a current I ?

Text Solution

Verified by Experts

`therefore" "i_(1)R_(1)=i_(2)R_(2)" or "i_(1)/i_(2)=R_(2)/R_(1)`
`i_(1)=(R_(2)i)/(R_(1)+R_(2))rArri_(2)=(R_(1)i)/(R_(1)+R_(2))`
