Components of electric circuit

Material that allows electric current to pass through easily

• conductor

• insulator

• flow

• circuit

what was the impact of the creation of an efficient light bulb?

• people were able to light their homes and continue working and going about their life during the night

• Houses didn't have to be lit by firefly light

• people no longer had to use a mirror to reflect light from one side of the earth to the other 

• It meant people could cook their chicken with electricity

How does a parallel circuit function?

• If one component fails the others will also fail as the current can only flow in one continuous loop.

• If one component fails the others will not as the current can still flow in a continuous loop through a second branch.

• If one component fails the others will also fail as the resistance is too high.

• I don't know yet?

Voltage is measured in

• volts

• amps

• ohms

• watt

LED is

• Light Enhancing Diode

• Light Emitting Diode

• Light Emitting Detector

• Light Enhancing Detector

What electronic component allows current to flow in one direction only? 

• Resistor
• LED
• Didode
• Switch

Resistors have coloured bands to show their value, this is the resistance they have in a circuit. But what is resistance measured in?

• Millimeters

• Inches

• Ohms

• Centimeters
