This device is used to measure the current in an electric circuit

Ammeter

100

What is Electrolysis?

Separation of elements 

100

An alarm clock draws 0.5 A of current when connected to a 120 volt circuit. Calculate its resistance.

R = V/I

= 120V/0.5A

=240 ohms

100

What unit do we use to measure current ?

Amp (A)
200

When two like charges get close to each other, they will ________

Repel

200

This device is used to measure the voltage in an electric circuit

200

What is electroplating?

Using electrical current to coat metals

200

If a toaster produces 12 ohms of resistance in a 120-volt circuit, what is the amount of current in the circuit?

I = V/R

=120V/12 ohms

= 10A

200
material that allows electricity to flow easily through it called
What is a conductor?
300

the largest form of static electricity we observe in real life (think weather)

What is lightning?

300

The part of a circuit that controls the movement of electrons (whether they move or not)

What is a switch?

300

What is voltage?

The pushing force for electrons

300

A light bulb has a resistance of 5 ohms and a maximum current of 10 A. How much voltage can be applied before the bulb will break?

V = I x R

=10A x 5 ohms 

= 50 V

300

Does not readily conduct electricity?

Insulator

a negatively charged balloon and a neutral wall will...

Attract 

400

the 4 main parts of any circuit are: 

Switch, load, battery, and connector wires

400

Whats is amperes?

The rate that current flows 

400

What happens to the voltage in a circuit if the current is increased from 1.5A  to 3.0 A 

The voltage will be doubled. 

400

Materials that have no resistance at low temperatures. 

Superconductor

500

removal of excess electrons from an object 

What is electric discharge?

500

The total ________ in a series circuit is always the same.

The total ________ in a parallel circuit is always the same. 

Current (I)

Voltage (V)

500

What is an electrolyte?

Paste or a liquid present in cells that conducts electricity.

500

What happens to the current in a circuit if a 10Ω resistor is removed and replaced by a 20Ω resistor?

The current will be reduced by half.

500

Why are the circuits at our homes mostly parallel circuits ?

Because when one load doesn't work, the others will still work.
