Welcher Stromkreis zeigt eine Parallelschaltung?
Wie lautet das Ohm'sche Gesetz?
Spannung = Widerstand * Stromstärke
Widerstand = Spannung * Stromstärke
Stromstärke = Spannung * Widerstand
Spannung = Widerstand : Stromstärke
Two identical lamps are in parallel in a complete circuit. If one breaks .......
the other lamp is brighter.
the other lamp is dimmer.
the other lamp no longer lights up.
the other lamp stays on.
Which is NOT true of a series circuit
One light lamp can be broken and other lights will still work.
The lamp become dimmer as more of them are added.
Adding more lamps will lessen the current in the loop
Fewer wires are needed compared to a parallel circuit.
If lamp 2 is unscrewed from its holder, what will happen to lamp1?
It will stay lit
It will go out
It will get dimmer
It will dissapear
Why is a lamp brighter when it is powered by two cells in series rather than one?
It is more efficient.
The flow of current is greater.
The lamp is designed to work with two cells not one.
The flow of current is less.
A circuit contains one cell and one lamp. If a second, identical lamp is added in parallel with the first,
both lamps will light up as bright as the first lamp did alone.
the second lamp will be brighter than the first.
both lamps will be equal in brightness but much dimmer than the first lamp was alone.
the second lamp will cause the first lamp to go out.
A circuit contains one cell and one lamp. If a second cell is added in series with the first and in the opposite direction
the lamp will be brighter.
the brightness of the lamp will not change.
the lamp will light for longer before the cells are flat.
the lamp will go out.
