When we connect a number of light bulbs in a circuit with a battery, we can use our models of current, resistance, and Kirchhoff's principles to predict the relative brightness of the bulbs. If the bulbs are all identical, then the brightness of a bulb will be an indicator of the current through that bulb (1.e., a brighter bulb has more current). A 1. The bulbs in the circuit shown on the right are all identical. Predict which bulb or bulbs will be the brightest, and which bulb or bulbs will be the dimmest. Also state if any bulbs will have equal brightnesses. Explain your prediction in detail. B All three bulbs have a resistance of 25 A, and the battery has a potential difference of 9 v. 2. Determine the current through each of the bulbs. Current in bulb A- Current in bulb B- Current in bulbC- A A 3. From your answers to part 2, do you think your prediction in part 1 was correct? Why or why not?

For the circuit shown in Figure 2, Determine the current through each circuit HINT: There are 5 unknown current values. This can be solved by writing a system of 5 independent equations for the 5 current values OR you may simplify the circuit (while being sure not to change any connection between batteries!) and then solve for 3 unknown current values and find the remaining 2 current values by analyzing the original circuit. 2. Determine the power input to the circuit by the batteries and the power dissipated from the circuit by the resistors. Demonstrate that energy is conserved by showing that “Power in = Power out”. HINT: What happens when current flows into the positive terminal of a battery instead of out of it?

What is the current read by the ammeter in the circuit below? Let R1 = 1 kiloohm, R2 = 2 kiloohm, R3 = 3 kiloohm, and the emf of the ideal source is 5 volts. Input R1, R2, and R3 for resistors R1. R2, and R3 respectively. Input E for the emf E. Use context clues to figure out if you need to input a numerical value, variable, word, etc. All numerical answers should be in three significant figures. R| R2 R3 First we calculate the current across each resistor. From Ohm's law, we arrive at a general formula for current: Plugging in values, the current across the resistor R1 is equal to: (Please note that the current is milliamperes) Similarly the current across R2 is: 12= mA And the current across R3 is: 13 = mA The current read by the ammeter is the sum of the currents across each resistor: 1=h+/2 +13 |= Alternatively, we can solve for the current across the ammeter by first calculating the equivalent resistance and then applying Ohm's law. The equivalent resistance of the three resistors…
