- 1Define electric currentRate of flow of electric charge
- 2Units of chargeCoulomb
- 3What is 1amp equivalent to?1 C per second
- 4What is Voltage?Pt. E per unit charge
- 5What are the 2 key components of a cellular circuitSandwiched Phospholipid Bilayer
[Ion]' and channels - 6How does a phospholipid bilayer act as a capacitor?By storing charges across its surface to produce voltage
- 7What do [ion]' and channels act as?Batteries with internal resistance
- 8Line thickness and chargeBattery is thin line, + charge
Fat line - charge - 9Describe the effect of multiplying ion conc. by x10 in a membrane selectively permeable to that ionx10 ion conc = x10 voltage measured
- 10Potential issues of this experimentBuild up of Ag2O/AgCl
If membrane is punctured ths will reduce voltage as Cl- can get through. - 11What is the log of 100?2
- 12Formula for V in this experimentV = (RT/zF)log10 ([out]/[in])
- 13Nigga tf does that shit mean (4)z = # proton + charges of that ion
T=Absolute temperature
F~9.65e4 coulombs per mole of protons
R= 8.3 joules per kelvin (kj) - 14What does RT/zF mean?Joules of energy per C
in other ords the VOLTAGE - 15What's the pint of this conversion?Allows you to convert from log10 of % to actual battery voltage
- 16What is conductance? Formula and units as well plsVoltage across a resistor
1/R
Siemens (heh) CAPITAL S - 17Resistance formula and symbol pls1/S
g - 18What do you use to measure current?Ammeter
- 19What do you use to measure a voltage?Voltmeter
- 20What is ac/dc?Alternating current
Constant current
LLIGHTNING BOLT \m/. - 21What is current measured in? What does it stand for?Amperes (A)
Flow of coulombs per second - 22How do you measure current?Total Iin = total Iout
- 23What is Charge Conservation?Charge can neither be created or destroyed
- 24What's Ohm's law?V=IR
Voltage drop as current flows through a resistor - 25Value of Voltage ____ in the direction of positive I flowDECREASES
(So down a resistor) - 26What occurs to R in parallel?R=V/I
1/2ma = 0.5kohm
R decreases - 27What occurs to conductance in parallel?S adds
