b. Three electric bulbs are connected in circuit with the 120 V battery as shown in the circuit diagram below . With the switch open (a) The manufacturer specifications for the cach bulb are 120V, 40W; 120V, 20W and 120V, 60W respectively. Using this specifications (means apply a 120 V to calculate the resistance of the bulbs), calculate the resistance of each bulb, note that the resistance of the bulbs remain constant. (R-360...

Consider a circuit containing five identical light bulbs and an ideal battery
A. Consider a circuit containing five identical light bulbs and an ideal battery. Assume that the resistance of each light bulb remains constant. Rank the bulbs (A through E) based on their brightness.Rank from brightest to dimmest. To rank items as equivalent, overlap them.B. What happens to bulb C?It gets dimmer.It gets brighter.There is no change.

A Investigation #11: Non-Identical Bulbs in Series and Parallel All of the circuits you have investigated so far have involved identical bulbs. If two bulbs are identical and one bulb is brighter, then the brighter bulb must have a larger current thru it. Furthermore, the larger current must be caused by a larger potential difference. In this investigation, you will study circuits for which the bulbs are not identical. We will illustrate that two Spherical bulbs are not identical by...
