Prоblems: Write аll yоur аnswers intо а separate sheet and upload it. Perform the following operations: (5 points) (8 x 104 + 4 x 103) ÷ 2 x 102 (2.2 x 102 ÷ 1.1 x 102) (5.5 x 104) If a resistor with a current of 20mA through it converts 12J of electrical energy into heat energy in 60 s, what is the voltage across the resistor? (5 Points) 74 x 1017 electrons flow through a wire in 250ms. What is the current in amperes? (5 Points) Determine the color bands for each of the following 4-band, 5% tolerance values: 330 Ω, 2.2 k Ω, 56 k Ω, 100 k Ω, and 39 k Ω (5 Points) At the end of a 31- day period, your utility bill shows that you have used 1800 kWh. What is your average daily power usage? (5 Points) You are measuring the current in a circuit that is operated on a 10V battery. The ammeter reads 50mA. Later, you notice that the current has dropped to 30mA. Eliminating the possibility of a resistance change, you must conclude that the voltage has changed. How much has the voltage of the battery changed? And what is the new value? (5 Points) A certain power supply provides a continues 2W to a load. It is operating at 60% efficiency in a 24-hour period, how many kilowatt-hours does the power supply use? (5 Points) Three 470 Ω resistors are connected in series with a 48V source. (a) What is the total current in the circuit? (b) What is the voltage across each resistor? (c) what is the minimum power rating of the resistor? (5 Points) Refer to the following figure, Assume the LED drops 2.0V across it when it’s on. The maximum current in the LED to be set at 10 mA and the minimum current is 2.0 mA. Choose the values of R1 and R2 to meet these requirements. (10 Points) 10. If you wish to increase the current in a resistor from 10 mA to 15 mA by changing the 20V source, by how many volts should you change the source? b) To what new value should you set it? (c) What is the value of the resistor? (10 Points) 11. Refer to the following figure, (a) Find the total current, (b) Voltage across each resistor, (c) Determine the voltage at each point with respect to ground. (10 Points)

An experiment by Dаrley аnd Bаtsоn (1973) lооked at seminary students’ willingness to help. In one condition, participants were made to hurry from one building to another by being told they were late to give a speech, which was part of the study requirements. In the other condition, participants were only told to go over to another building in order to give the speech. Both groups encountered a person lying on the ground on their way to the other building. The experimenter observed the participants from both groups and counted the number of people who stopped to check on the person lying on the ground. In this experiment, what was the independent variable?
