A circuit has an applied voltage of 24 volts and a load consisting of a 10-ohm resistor in series with a 30 ohm resistor. what is the voltage drop across the 10-ohm resistor

6 volts (correct)

8 volts

24 volts

12 volts

which is correct in reference to electrical resistance

An electrical device that has a high resistance will use more power than one with a low resistance

Two electrical device will have the same combines resistance if they are connected in series as they will have if they are connected in parallels
