If voltage remains the same and resistance increases does the number of electrons passing a point in the circuit in one second (current, I) increase, decrease or stay the same? Decrease When the turkey baster was filled with water and held up and allowed to drain it did so rather quickly. When paper towel was rolled up and placed in the turkey baster it took much longer for the water to flow out. If voltage (V) in a circuit remains constant and resistance(R) increases does current (I) increase, decrease or stay the same? Decrease It is more difficult for the electrons to be pushed through the circuit but the push remains the same(voltage) so fewer electrons pass a given point in the circuit in one second Series Circuits There is only one pathway for the current to travel The current is the same at all points along the circuit As the number of light bulbs increases, the potential difference across each bulb decreases and the bulbs burn less brightly If one bulb burns out the current stops After 2 seconds which cup will have more water A,B or C? They will have almost the same amount of water. Which jug will empty first 1 or 2? 2 There is more than one pathway for the current The current splits into the different pathways The total current in the main circuit is equal to the sum of all the current in the parallel branches (connectors) The potential difference across each bulb equals the voltage produced by the source The brightness of the bulbs stay the same as more bulbs are added so the battery must push out more electrons for each additional light (pathway) added. If one bulb burns out the remaining bulbs stay lit If a 3 light 1 battery series circuit and a 3 light 1 battery parallel circuit were turned on at the same time, which circuit would stop working first? (note: all the lights and batteries are the same) the parallel circuit
