A series RL circuit contains two resistors.The resistors are 60ohm and 30ohm.when calculating the circuit values, what is the total resistance?

90 ohms.

To find the total resistance in a series RL circuit, you need to add the individual resistances together. In this case, you have two resistors: 60 ohm and 30 ohm.

To calculate the total resistance:
1. Add the values of the resistors: 60 ohm + 30 ohm = 90 ohm

Therefore, the total resistance of the series RL circuit is 90 ohm.
