Say True or False:
- A battery in a circuit consists of one cell only
- The heat produced in a conductor by an electric current does not depend on the material of the wire
- The greater the current in the wire, the more heated up it will get
- A fuse wire is made up of metal that does not melt easily
- The electric bulb is based on the magnetic effect of electric current
1. False: Battery is a combination of two or more cells.
2. False: Heat flow depends on the thermal conductivity of the material of the wire.
3. True
4. False: Fuse wire is made up of material with low melting point so that it melts easily as high current passes through it.
5. False: Electric bulb is based on heating effects if elecric current.
2. False: Heat flow depends on the thermal conductivity of the material of the wire.
