Question

In series connection,what is the equivalent resistance of the combination of three resistors

Answer 1

In series connection....Total resistance is measured by using this formula...↓↓
R = R1+R2+R3

Answer 2

In series combination the equivalent resistance formula is R1+R2+R3=Tr(total resistance)
For example if R1=2ohm and R2=4ohm and R3=6ohm. So Tr will be
=2+4+6
Tr=12ohms ok

Hope helps you

Have a great day
