How would you solve this circuit? List your steps, please.

Combo Circuit

1. understand your givens and unknowns

Look at your what you information is given and what the question is asking, be mindful of your units

Combo Circuit

2. Simplify any series -related components

check for batteries or resistors in series, watch the units and combine them when possible

Combo Circuit

3. Work through parallel components, find R_t

watch the units and combine them when possible, following up with ones that are related now by series

Combo Circuit

4. Act out your inner Kirchhoff

remember that you can focus on each loop alone to solve circuits using voltage drops and batteries or focus the current with the Node law

Combo Circuit

5. Bring it home with your good buddy, Georg Ohm

Use V, I, and R to solve
anything else you need

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.
