Circuits

Question 1

Voltage units?

Answer 1

J/C

Question 2

Kirchoff’s Laws on current states that?

Answer 2

I_{into junction} = I_{out of junction}

So at any split current will also split

Question 3

Kirkchhoff’s law of loops?

Answer 3

Voltage is used up in a circuit

Question 4

What is the resistance formula?

Answer 4

R = ρL / A

Question 5

Power = ? = ? = ?

Answer 5

IV = I²R = V²/R

Question 6

Resistors in series are (additive/inverse) ?

Answer 6

Additive

Question 7

Resistors in parallel are (additive/inverse) ?

Answer 7

Inversely added

Question 8

What is conduction?

Answer 8

Direct transfer of energy, molecule to molecule, mano y mano

Question 9

What is convection?

Answer 9

direct transfer of heat by fluids (gas and liquids)

Question 10

What is radiation?

Answer 10

transfer of energy by electromagnetic waves

Question 11

What is the specific heat of water, what is the specific heats symbol?

Answer 11

c = 1 cal / gK

Question 12

When you think of transfering heat, or phase changes, what 2 equations should come to mind?

Answer 12

q = mcΔT

or

q = mL

Question 13

What do the thermodynamic processes (isobaric, isovolumetric, adiabatic, isothermal) look like on a PV graph?

Answer 13

Question 14

Which way does current run on circuit symbols?

Answer 14

+ to -

Question 15

Electrostatics:

What does FUEV stand for?

Answer 15

Electrostatic Force

Electrostatic Potential Energy

Electric field

Electrostatic Potential

To go to the right, multiply by R

To go down divide by (q) charge
