question
suppose a single light bulb burns out. How do you think this will affect the lights that are strung along a single wire.
answer
There is a good chance that the others will burn out too.
question
How will a single burned-out bulb affect the string of lights if each light is attached to its own wire?
answer
It won't affect the other bulbs.
question
Click the light switch to turn it ON. What happens?
answer
The electricity flows and the light turns on
question
How does changing the battery's voltage affect current?
answer
the current increases.
question
How does changing the battery's voltage affect the brightness of the light.
answer
the higher the voltage the brighter the light.
question
Remove the wire. What happens?
answer
The circuit stops.
question
How do you think increasing the resistance in a circuit will affect the current in the wire.
answer
It will decrease the current.
question
Is the current the same throughout, or does it change?
answer
It is the same.
question
what is the current in the wire now
answer
2.7 amp
question
Collect Data
answer
Voltage Resistance Current 10 volts 10 ohms 1 amp 20 volts 10 ohms 2 amp 30 volts 10 ohms 3 amp 50 volts 20 ohms 2.5 amp 50 volts 100 ohms 0.5 amp 50 volts 200 ohms 0.25 amp
question
What is the mathematical relationship between voltage, resistance, and current.
answer
V=IxR
question
Test your equation with other combinations of the equation.
answer
I= V/R R= V/I
question
Use ohms law to find the resistance of the light bulb in Gizmo.
answer
I=V/R
question
How does the new light bulb affect the others?
answer
it takes up electricity
question
Use the ammeter to measure the current in various parts of the circuit. Is the current the same throughout?
answer
Yes, the current is the same throughout.
question
How do you think the total resistance of a series circuit is calculated?
answer
through the summation of the resistors values.
question
A. based on the voltage and current, what is the resistance of the circuit?
answer
40 ohms
question
B. what is the resistance?
answer
40 ohms
question
Make a rule: How do you calculate the total resistance of a series circuit?
answer
through the summation of the resistors values.
question
Extend your thinking: Replace the battery. Turn on Show current, and remove one resistor. Why would it be a problem if your household appliances were connected in a series circuit?
answer
It would be inefficient and all the appliances may not need the same voltage.
