Chapter 20.1, Problem 1TH
In tutorial, you compared the relative brightness of the bulbs in the three circuits shown. In the diagrams, boxes have been drawn around the networks of bulbs in each circuit.
On the basis of your observations and the rule you developed in tutorial relating current through the battery to total resistance, rank the networks (boxes) A−C according to their equivalent resistance. Explain your reasoning on the basis of the model. (Do not use math.)

Give a broader explanation why the three bulbs in the circuit diagrams below are going to have the equal brigtness
A resistor is dissipating 114 milliwatts [mW] of power. The voltage across the resistor is 13 volts [V].
(a) What is the value of the resistance? Express your answer in units of ohms [Ω] using an appropriate SI prefix such that there are only one, two, or three digits shown to the left of the decimal.
(b) What is the current through the resistor? Express your answer in units of amperes [A] using an appropriate SI prefix such that there are only one, two, or three digits shown to the left of the decimal.
Suppose you have a circuit in which you have connected 3 batteries, each of which that has voltage of 2.8V, in series with each other such that the positive terminal of one battery is connected to the negative terminal of the next (and so on), what is the resulting voltage?
Note: It is understood that the unit of your answer is in Joules (J), however do not explicitly include units in your answer. Enter only a number.

- The electric current I (in amperes) passing through a resistor is related to the voltage V across a resistor (in volt) and the resistance R (in ohms) by the formula I = ? ? . If the resistor is connected across the terminals of a car battery (12 volts), construct a table of values of the current across the resistor for different resistor values from 2000 ohms to 5000 ohms. Use intervals of 1000 ohms. Plot these values as points in the Cartesian plane and connect the points.
