Textbook Question
Chapter 6.1, Problem 1dT
Carefully examine a bulb. Two wires extend from the filament of the bulb into the base. You probably cannot see into the base, however, you should be able to make a good guess as to where the wires are attached. Describe where the wires attach. Explain based on your observations in Parts A-C.
On the basis of the observations that we have made, we will make the following assumptions:
1. A flow exists in a complete circuit from one terminal of the battery, through the rest of the circuit, back to the other terminal of the battery, through the battery and back around the circuit. We will call this flow
2. For identical bulbs, bulb brightness can be used as an indicator of the amount of current through that bulb: the brighter the bulb, the greater the current.

Consider the following.
(a) A rectangular block has the dimensions ℓ ✕ w ✕ h. When a battery with a voltage V is connected across the end faces as shown in the left figure above, a current I1 flows through the circuit. If the same battery is connected across the top and bottom faces of the block as shown in the right figure, what is the current I2 that flows through the circuit? Give your answer in terms of I1. (Use the following as necessary: ℓ, w, h, I1) I2 = ?
(b) Suppose ℓ = 4.20 cm, w = 2.2 cm, and h = 1.80 cm; the battery voltage is 1.5 V and I1 = 2.50 A, determine the value of I2. (A)
A long, cylindrical conductor of radius R carries a current I as shown in the figure below. The current density J, however, is not uniform over the cross section of the conductor but is a function of the radius according to J = 4br2, where b is a constant.
a) r1 < R
Note: See image for the original question and figure. I just need help with part a, not part b.

- We would like to use the relation V(t)=I(t)R to find the voltage and current in the circuit as functions of time. To do so, we use the fact that current can be expressed in terms of the voltage. This will produce a differential equation relating the voltage V(t) to its derivative. Rewrite the right-hand side of this relation, replacing I(t) with an expression involving the time derivative of the voltage.
