Chapter 6.2, Problem 2bT

Set up the circuit containing two bulbs in series as shown.

Rank from largest to smallest the currents through bulb 1, bulb 2, and the bulb in the single-bulb circuit from part $A\left(i_{\text{Bulb}\text{1}},i_{\text{Bulb}\text{2}},i_{\text{single}}\right)$ . Explain.
Measure the potential difference across each element in the circuit.

1. How does the potential difference across the battery in this circuit compare to the potential difference across the battery in the single-bulb circuit? (See part A.)
2. Rank the potential differences across bulb 1, bulb 2, and the bulb in the single-bulb circuit from part A.
3. How does the potential difference ranking compare10 the brightness ranking of the bulbs?
