Which one will have transformation of electrical energy to mechanical energy?
a) electric fan
b) candle
c) flashlight
What is A) ELECTRIC FAN?
300
Define the word conduction.
What is the transfer of the thermal energy from particle to particle between two objects that are touching.
300
If I have a circuit with an open breaker, will it light the bulb? and why?
What is NO, if the breaker is open it will stop the flow of electricity. If the flow of electricity is stopped, then it can not reach the bulb.

Which one transfers thermal energy by the movement of fluids.
Convection
Conduction
What is CONVECTION?
300
On a bar magnet, where is the force the strongest?
What is at the MAGNETIC POLES?
400
Which one will have the transformation of electrical energy to heat energy (thermal)?
a) flashlight
b) electric heater
c) calculator
What is B) ELECTRIC HEATER?
400
Define the word radiation.
What is the transfer of thermal energy without matter?
400
If I have a circuit with a closed breaker, will the light bulb light up?
What is YES, if the breaker is closed then the flow of electricity can reach the light bulb, causing it to light up.

What is the difference between an electric generator and an electric motor?
An electric motor changes electrical energy into mechanical energy.
A generator changes mechanical energy into electrical energy.
500
Which one will have the transformation of mechanical energy to electrical energy?
a) electric heater
b) electric fan
c) generator
What is C) GENERATOR?

Define the term refraction.
What is when light waves bend as they pass from one material to another.
500
What is the difference between an insulator and a conductor? How are they similiar?
What is the difference between an insulator and conductor is an insulator stops or prevents the flow of electricity, a conductor allows the flow of electricity.
They are similiar because they both are involved in electricity.
