What effect would adding another battery have on these values?
Adding another battery would increase the values because it'll be receiving more energy than before
Why might you want to use batteries in series?
You might want to use batteries in series in order produce a greater voltage.
Why might you want to use batteries in parallel?
Using batteries in parallel might increase your voltage and make them last longer
Is there a difference in brightness between bulbs in series and parallel. Explain?
Parallel circuits hare brighter because the bulbs have full access to the batteries, while series circuits have to share the batteries power, so series circuits are dimmer.
Is there a difference with and without the fan blades? Explain.
There is only a small difference because the fan blades are adding more weight to the motor, so its taking a bit more power.
In circuit B, a lamp is added. What effect does adding a lamp have on the speed of the motor turning the fan blades?
Adding a lamp will make the motor speed slower because the motor will now have to share the batterie power with the lamp, making it run on less energy
Also in Circuit B, the button switch bypasses the lamp. What happens to the motor when it is pressed, and why does this happen?
When the button is press the energy from the battery will not go to the lamp making the motor spin faster because it’s receiving more energy from the battery.
