Check to make sure that the battery is 9 Volts, one resistor is 10 Ohms, and the other resistor is 20 Ohms.O Current 0.30 A Drag and drop the non-contact ammeter onto the circuit. Place the crosshairs of the non-contact ammeter on the wire several places around the circuit to find the current in the wire. What is it? 0.15 A O 0.30 A O 0.45 A O 0.60 AQUESTION 2 Circuit Construction Choose one . 5 points Is this circuit arranged in series, in parallel, or in both formations? Series Parallel Both series and parallel V QUESTION 3 Resistance Choose one . 5 points Based on your answer from #2, use one of the following equations to calculate the total resistance of the circuit.

A voltmeter measures the difference in the voltage between 2 places on a circuit. This is called the voltage drop. Place the contacts of the voltmeter on the circuit on either side of the battery. Note: The voltmeter tells you the voltage drop between the two points in the circuit touched by the probes. Voltage works in a similar fashion to gravitational potential energy based on height. Balls will only roll down board if one end is higher than the other (so it is sloped). The ball (electron) at the higher end of the board (wire) has lots of potential energy (voltage). The ball will roll down the board (electron will move through the wire) to the lower end of the board that has less gravitational potential (less voltage). You could use a ruler to measure the height difference between the high point of the board and the low point where the ball moves to. This would be the change in height or how hard the ball dropped in height. For the Electron, you would use a voltmeter to measure how much the voltage dropped from one point to another. What is the voltage drop across the battery? Voltage -9.00 VO 1V O 3V O 9v O 12 V V QUESTION 6 Voltage Choose one . 5 points Place the contacts on either side of the 10 Ohm resistor.

Use the voltmeter to remeasure the voltage across each of the resistors. Now how does the total voltage across the resistors compare to that of the battery? Note: If you receive decimal points for any of your voltmeter readings, please round to the nearest whole number before adding and comparing- Greater than Less than Equal to QUESTION 10 Circuit Construction Choose one . 5 points Change the battery's voltage back to 9 Volts, use three more wires, and rearrange your resistors so that the circuit is set up like this: Show Current O Electrons Wire O Conventional Labels Values 9.0 VIs this circuit arranged in series, in parallel, or in both formations? 0 Series 0 Parallel 0 Both Series and Parallel QUESTION 11 Resistance Choose one . 5 points Based on your answer in #10, use one of the following equations to calculate the total resistance of the circuit: Resistance in Series Rtotal = R1 + Re Resistance in Parallel 1 1 1 Rtotal + R2 What is the total resistance in a circuit that has three 40 and four 30 resistors all arranged in series?
