Problem suppose that the light bulb in figure 224b is a, Ask an Expert

Academics

Problem: Suppose that the light bulb in Figure 22.4b is a 60.0-W bulb with a resistance of 287 ohm. The magnetic field has a magnitude of 0.290 T, and the length of the rod is 1.41 m. The only resistance in the circuit is that due to the bulb.

Part A: What is the shortest distance along the rails that the rod would have to slide for the bulb to remain lit for one-half second?

I need help to find the shortest distance along the rails that the rod would have to slide for the bulb to remain lit for one-half second.
