Question

5. What factors does the amount of heating in an electric conductor by an electric current
depend on? Write two practical applications of the heating effect of current.​

Answer 1

Step-by-step explanation:

The heating effect in an electric conductor by an electric current depends upon:

1. The resistance of the electric conductor. Higher resistance of the conductor, More the heat produced.

2. Time for which the electricity flows through the conductor. More the time of flow, more heat is produced.

3. Amount of current flowing through the conductor.

Higher the amount, more is the heating effect.

Some applications of heating effect of electric current are in room heaters, geysers, filament bulb,etc.

Answer 2

The factors that affect the production of heat in a wire through which an electric current flow are, The length of the wire. The thickness of the wire. The duration of flow of current

• The resistance, R of the conductor. A higher resistance produces more heat.
• The time, t for which current flows. The longer the time the larger the amount of heat produced.
• The amount of current, I.
