Asked by Claire

When 3 resistors of 1 ohm resistance each are connected in series to a 12 volt power supply, the total resistance of the circuit is _______ ohms.

I really appreciate any help with this stuff - it's difficult for me! Thanks

The combined resistance of resistors connected in series is the sum of their resistances. Just add the three resistances.

That's right. 1 + 1 + 1 = __ ohms
The voltage doesn't matter.
