Multiple Choice

Is 0.42 equal to R _2,3?

• yes

• no

• not sure

Multiple Choice

What is the unit that goes with 2.38?

• ohms

• volts

• amps

• squids

Multiple Choice

What formula is used to determine the R _total now?

• V battery / R₁

• 1/R_total = 1/R₁ + 1/R₂ + ... + 1/R_n

• it matters what the racoon thinks taste better doritos or the knock-off version

• R_total = R₁ + R₂ + ... + R_n

Multiple Choice

How will you determine what I _main is?

• Subtract the voltage of the battery from the Rtotal

• divide V_battery by the R _total

• multiply V_battery by the R _total

Multiple Choice

What is the unit for current?

• volt
• amp

• ohm
• watt

Multiple Choice

Voltage from a battery is _________ of Kirchhoff's voltage law

• measured in ohms
• added to the equation

• subtracted from the equation

• ignored in circuit analysis

Multiple Choice

What would the current at R₃ be?

• 2.06 / 4

• 2.06 x 4

• 0.87

• unknownable

Multiple Choice

Why is the voltage drop divided by 6 to find the current at R2?

• 6 is the resistance at the circuit, V/R = I

• 6 is the resistance at the circuit, V x R = I

• The voltage drop is irrelevant to the current at R2.
• The current at R2 is equal to the total voltage in the circuit.
