Current into a node = Current out of a node

Virchhoff's Current Law

300

Voltage around a circuit must = 0

Kirchhoff's Voltage Law

400

In a series circuit, does the voltage or current change?

Voltage

500

R₁+R₂+R₃+...=R_t

Total resistance in a series circuit

Math

100

If there is 1A running through a resistor of 10ohms, what is the voltage across the resistor?

10V

200

Suppose you have 3 resistors in series with resistances of 345, 567, 9834 ohms respectively. What is the total resistance of the ideal system.

10,741 ohms

300

2 lines of current are going into a node and 1 line is coming out. If 10A is going into the node and 9A is coming out, what is the current of the other line going in?

-1A

400

Two batteries with the same voltage facing opposite directions are placed in a circuit. 3 light bulbs are also placed in the circuit. Which lightbulb lights up first, the one closest, in the middle, or furthest from the positive side of the first battery?

Trick question... the battery voltages cancel out, meaning that the voltage through the circuit is net 0

500

A circuit has two resistors in series, one that is 30ohms and one that is 20ohms. The battery powering the system is a 10V battery. What is the current running through the resistor?

0.2A

Trivia

100

What is it called when there is a free line of current with little resistance, often causing the system to overheat and damage components.

Short circuit

200

What type of current powers the appliances in your household?

Alternating Current

300

What type of circuits are used to power the lighting in your house? (hint if one light goes out all do not go out)

Parallel circuits

400

What is the old light bulb used to be in use that was super inefficient and was then changed to the LED.

Incandescent light bulb

500

A device used to split/lower the voltage through a system by applying 2 separate paths with 2 separate resistors.

Voltage divider

Random

100

If 0 and 0 go into an AND logic gate, what will be the outcome?

0

200

If 0 and 1 go into an OR logic gate, what will be the result?

1

300

What type of graph does AC resemble?

Sine wave

400

Current is moving leftward through a wire. In which direction is magnetism inducted?

DAILY DOUBLE, it wraps around the wire. try right hand grip rule!

500
