ELECTRIC CURRENT AND ITS EFFECTS
303286
Which of the following equipment does not work on principle of Joule's law?
1 Electric Heater
2 Electric Iron
3 Electric Bulb
4 Electric Fan
Explanation:
Electric Fan The electric iron, electric heater and electric bulb are some of the familiar devices based on Joule’s Law, but electric fan is not based on Joule's Law.
ELECTRIC CURRENT AND ITS EFFECTS
303287
What does this symbol mean in electric circuits?
1 Rheostat
2 Battery
3 Capacitor
4 Inductance
Explanation:
Rheostat Rheostat is a variable resistor, which is used to control the flow of electric current by manually increasing or decreasing the resistance. The arrow sign indicates the variability.
ELECTRIC CURRENT AND ITS EFFECTS
303288
A device which prevents or allows the current to flow through it:
1 Motor
2 Terminal
3 Conductor
4 Switch
Explanation:
Switch A switch prevents or allows current to flow through it. It is a device used for making and breaking connections in an electric circuit. For example, when anyone presses the button (switch) for light/fan, with the completion of the circuit, the device starts to function.
