Answer :
To calculate the total resistance in the circuit we would have 25 ohm.
What is the calculation?
To calculate the total resistance in a series circuit arrangement, we have to add up the individual values. So, the total resistance of the circuit would amount to
Rtotal = R1 + R2 + R3
Rtotal = 5ohm + 8ohm + 12ohm
Rtotal = 25ohm
So, the calculation is a simple one because we only have to add up the values of the three resistance values. The summation of the values in this case gives us 25 ohms.
