EOY DAY 1 ELECTRICITY

A 12-volt battery maintains a 4.5A current through a resistor. What is the resistance of the resistor?

Write this into your notebook.

Which of the following is equal at each point along this circuit?

What type of circuit is this?

Draw this in your notebook.

If lightbulb #3 goes out, select any/all other lightbulbs that will be affected.

Write this into your notebook under your drawing.

Calculate the total resistance of the series circuit.

R_T=R₁+R₂+R₃

Draw this into your notebook and show work.

Which of the following is equal at each point along the circuit?

If bulb #3 goes out, which other bulb(s) will be effected?

Write this into your notebook under your drawing.

Students are testing how well old and new batteries can light multiple bulbs in parallel. Which hypothesis would allow them to design a valid experiment?

Calculate the resistance of the parallel circuit.

1/R_T=1/R₁+1/R₂+1/R₃
