A 50 ohm lamp and a 10 ohm electric iron are connected in series to a generator delivering 120 V.

The current through the lamp and the iron is ___
The voltage ccross the lamp is ___
The voltage drop acrowss the iron is ___

How do I set these up? Thank you.

  • physics -

    Rt = 50 + 10 = 60 Ohms.

    I = V/Rt = 120 / 60 = 2Amps.

    V = IR = 2 * 50 = 100 Volts across lamp.

    V = 2 * 10 = 20 Volts across iron.
