What is the total resistance of a series circuit with a 2Ω and 3Ω resistor?

5Ω

Should an ammeter be connected to a circuit in series?

Yes

Resistors are connected such that there is a single pathway for electron flow

series circuit

If the current through a bulb is 0.12 A in a series circuit, what is the current through the cell?

0.12 A

Series Circuit

A circuit in which all parts are connected end to end to provide a single path of current

Series Connection

A connection of two or more electric devices that provides only one path for a current.

How do we find the total resistance in a series circuit?

Adding the resistance of all resistors in a series circuit gives us total resistance.

series, ammeters have very little resistance so they do not affect the flow of current through them

Ammeters are always connected in a ___ circuit because ___

Series ; parallel

An ammeter is connected in _______ and a voltmeter is connected in ______

what is a series circuit

As more objects are added to this circuit the energy going to each object decreases •If a light burns out in the path is incomplete so all other objects are also not powered

As resistance goes up in series, the ____ goes up in series

Current.

What happens to the current, voltage, and resistance in series and parallel circuits?

Current: The current through the whole circuit is the same throughout and is equal to the total current supplied by the source.

Voltage

In a series circuit the ______ is different throughout the circuit

What can be said about the current in a series circuit?

In a series circuit, the current is the same in each component.

Greater

In a series circuit, the equivalent resistance is ______ than that of any individual resistor

In a series circuit, the effective resistance ( ). (Increase/decrease)

Increase

Does it matter where in a series circuit that I connect the ammeter?

No

According to _ Law, in a series circuit there is a voltage drop across each device that depends directly on its _

Ohm's, resistance

What is a series circuit?

Only one loop. If one component breaks, none work.

types of electrical circuits

Parallel Series

What happens to the current, voltage, and resistance in series and parallel circuits?

Resistance: Resistors placed in series increase the total resistance of the circuit. As a result, the total current throughout the circuit decreases.

What is the difference between parallel and series?

Series Current Same anywhere Voltage Shared by all components. Parallel Current Shared equally by all the loops Voltage Same for each loop.

all components of a series circuit are connected with each other in a single line, there is only one possible path

Series circuit

Ammeters and series circuits

Series: the reading represents the amount of current flowing through all loads or objects connected in the circuit

How can we find the potential difference in a series circuit?

Total potential difference in a series circuit is found by adding the potential difference of each component.

How do you find the voltage drop across each device in the series circuit?

V1=ItR1 (V2=ItR2, etc)

What happens to the current, voltage, and resistance in series and parallel circuits?

Voltage: The voltage across each of the loads in the circuit add up to the voltage supplied by the source.

What is the formula for the total current in a series circuit?

Vt=ItRt

Formula for the total voltage in a series circuit

Vt=V1+V2+V3..

Series Circuit

a circuit in which the loads are connected end to end so that there is only 1 path for electrons to flow (ex. when you plug in a toaster and an electric kettle into the same outlet, the toaster and kettle are 2 loads in the same circuit and are 2 loads in series. this means if the fuse for the outlet blows neither device will work.

series connection

a type of connection in which there is only a single current path

Series circuit

circuit that has only one path for electric current to follow

In a series circuit, _ is the same throughout each resistor

current

In a series circuit, what stays the same?

current

less brightly

if another globe is added to a series circuit, the globes shine ____

don't light up

if one globe in a series circuit blows, the others ___

Current in a series circuit is ___ between globes

same

In a series circuit, the current at any point in the circuit is ( ). (same/different)

same

What do you notice about the series circuit formula for total current and the parallel circuit formula for total current?

same (Vt=ItRt)

series or parallel: all of the loads must be on and working at the same time in order for current to flow through the circuit

series

series or parallel: the current is the same throughout the circuit

series

series or parallel: the sum of the potential differences across the loads equal the total potential difference across the source

series

series or parallel: there is only one pathway on which charges can flow

series

series or parallel: when more loads are added to the circuit, the current leaving the source decreases

series

series or parallel: when more loads are added to the circuit, the potential difference across each individual load decrease

series

series, parallel

Voltage in a series circuit is ___ between globes
