1

## What are the 2 needed pieces required to have a circuit?

###
A power supply (the "push")

A wire

2

## Anything that uses the electric energy in a circuit

### Resistor

3

## Law that is the cornerstone for electric circuits

### Ohm's Law, V=IR

4

## Ohm's Law (formula)

###
V=IR

V= potential difference (measured in volts)

I=current (measured in amperes)

R=resistance (measured in ohms)

5

## What creates the "push" in a circuit?

### a Potential Difference (voltage)

6

## The quantity of charge moving past a point per second

### Current (amps)

7

## T/F: Current is a measurement of the distance and speed at which a charge travels

### False. Current is the quantity of charge. It is a quantity rate.

8

## By designation, current is the movement of what type of charge?

### Positive Charge

9

## Formula for Current

###
I=q/t

I=current measured in amps

q=quantity of charge

t=time

10

## Measurement of the "electrical pump"

### Voltage

11

## The key to voltage is a _______________ in volts

### Difference

12

## What typically provides voltage?

### A generator or battery

13

## This inhibits the flow of current and uses voltage

### Resistor

14

## What is the relationship between the resistance and current?

### When the voltage remains constant, resistance and current are inversely related. When one goes up, the other goes down.

15

## What are the two main types of circuits?

###
Series Circuit

Parallel Circuit

16

## A single pathway for current to flow

### Series Circuit

17

## A series of branches for current to flow through

### Parallel Circuit

18

## How do we determine the total resistance in a series circuit?

### Is is the sum of all the resistors (e.g., all the bulbs added up)

19

## In a series circuit, what happens when one of the resistors (a bulb, e.g.) goes out?

### The whole circuit shuts down.

20

## What is the relationship between Voltage and Resistance?

### Big resistance, big voltage. The voltage distributed across each resistor is proportional to the resistance of that device.

21

## Circuit that has multiple paths for the current to leave the battery and finally return to it

### Parallel Circuit

22

## In a parallel circuit, most of the current follows what path?

### The path of least resistance

23

## What type of circuits run in our homes?

### Parallel Circuits
