The drawing shows a circuit that includes a bimetallic strip (made from brass and steel) with a resistance heater wire wrapped around it. When the switch is initially closed, a current appears in the circuit because charges flow through the heater wire (which becomes hot), the strip itself, the contact point, and the light bulb.

The pedestrian crossing of Washington Road and Ivy Lane (near the Physics building) needs a back-up battery in event of power failure. In order for the three lights to be bright enough to be seen in daylight, each of the three RL = 50 N lights must dissipate P = the 3 lights are connected in parallel (see the drawing), and the open circuit voltage of the battery (that is, the voltage when there is no current) is Vo = 110 volts. What is the maximum internal battery resistance R; allowable given that each lamp must dissipate 220 watts? 220 watts. Suppose %3D %3D Ri Vo RL pyri
In the circuit in the figure, two identical parallel metallic plates are connected by an identical metallic spring to a 100 V battery. In the open state, the plates are unloaded, the clearance between them is d = 4 mm and the surface of one plate is 1778 m2. When the switch is turned off, the distance between the plates is reduced by 0.5 times. What is the spring constant of each spring in units of Newton / meter? ɛ, = 9 × 10-12 C / N m?
Some strings of holiday lights are wired in series to save wiring costs. An old version utilized bulbs that break the electrical connection, like an open switch, when they burn out. If one such bulb burns out, what happens to the others? If such a string operates on 120 V and has 40 identical bulbs, what is the normal operating voltage of each? Newer versions use bulbs that short circuit, like a closed switch, when they burn out. If one such bulb burns out, what happens to the others? If such a string operates on 120 V and has 39 remaining identical bulbs, what is then the operating voltage of each?
