If one of the resistors was replaced by a wire, how would the current change (increase, decrease, stay the same)?M. If a third battery was added to the circuit, how would the current change?mR₁ = 1000R₁ = 40002mER₂ =20094. So, which switches need to be closed to allow:A) * only resistor 1 to have current in it?B) only resistor 2 to have current thru it?C) to by-pass both resistors?D) for electricity to go thru both resistors?H2. Now, using what you learned from parts G-J above (and the lab),A. How much voltage is used by the 15002?B. What is the voltage of the battery?C. How much current is flowing (in mA)?FG3. The new symbol you see in the diagram at the left is a multicell battery (like a 9V), which ismade up of a number of smaller single cell batteries (like a 1.5V). Let's say its total voltage is V.A. Which resistor takes the most voltage?B. What is the total resistance?C. In variables, what is the current in the circuit?D. How does the voltage used by the 2R compare with R?E. In variables, what is the voltage used by the 2R resistor?In the diagram at the left you will need to decide which switches to close to allowdifferent resistors to have current flowing thru them. This is like maze games-justfollow the path. But here are the rules: 1) you must start at the + side of the bat-tery (big side) and get back to the side; 2) you can't go backwards along thesame line (since current only flows from high V to low V); 3) you can't make ashort-circuit (make a circuit without a resistor in it).Copyright © 2013, C. Stephen Murray PreAP Circuits 5-p2So what are these electrons flowing thru the circuit? Let's learn about charge (positives and negatives).Electric Charge The unit of charge is a fundamental quantity.5.Electron Charge1 electron=-1.6×10¹ CThe smallest units of charge are theproton and the electron. You can-not have part of an electron, be-cause it would lose its negativecharge. Therefore, you cannothave less than -1.602x10¹9C ofcharge and any amount of chargemust be multiples of this number.You can have 12 or 13 electrons,but not 12.2 or 12.5 electrons!* What is the charge of 15 electrons?The charge of a proton is the sameas an electron, only positive:1 proton = +1.6x10.¹⁹C.7. What is the charge of 8 protons?le le e1A: 0.02 A (which is 20 mA)1C: V = IR = .02(100) = 2VID: P = VI or = I²R = 0.04W8. Why can't you have a charge of 1.5 electrons?NotpossibleElectric charge is quantized,meaning the amount ofcharge must always be inmultiples of e. You can neverhave part of an electron.cstephenmurray.comEx: What is the charge of an object thatgains 1.2 x 10 electrons?Do a conversion :1.2x1016. * Given the charge of 1.12x10-¹8 coulombs.

And since it is a seriescircuit, isn't that the total?4A: Switches: A, C, and D. You can't have D on or R2 comes on. You can't have E on or it will bypassR1 completely with a short circuit.5: -24x10-¹9 C or -2.4x10-18 C coulombs6: 7 electrons lostCopyright © 2013, C. Stephen Murray
