WebAug 2, 2024 · The power dissipated by a lightbulb in this circuit is given by P = I 2 R, where R is the lightbulb's resistance. Therefore, a lower current means less power dissipation, and less of a chance of exploding. The current is constant throughout a series circuit (i.e. at all points in the circuit). WebThe brightness of a light bulb is related to the power dissipated by that bulb. Recall that power depends upon the square of the current that passes through the bulb and the resistance of the bulb. Since each light bulb in this circuit has the same resistance, the lightbulb with the largest current passing through it will be the brightest.

WebOct 3, 2013 · A resistor is nothing magic. Take a long wire and measure the resistance, and you will realize that resistance is just a normal property of wires (except for superconductors). Some resistors are made up of just that. A long wire. But you can also find resistors made of other types of materials. Like this carbon film resistor:
