What is the lowest total resistance that can be secured by combinations of four coils of resistance `4Omega,8Omega,12Omega,24Omega`

Text Solution

Verified by Experts

When al the resistors are connected in series
Thus, total resitance `=4Omega+8Omega+12Omega+24Omega`
`=48Omega`
Thus, highest resistance`=48Omega`
Lowest resistance=`2Omega`
