When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
They Attract: F = iL x B
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
It will glow VERY BRIGHTLY for a few seconds - and then burn out.
Lemon juice is an acid. The metal in the paper clip reacts with the acid to produce an electric current. It's the same process as the electricity produced in a battery.
when electric current is passed through acidified water hydrogen gas is released at the cathode..
when electric current is passed through acidified water hydrogen gas is released at the cathode..
It will get hot.
Basically, if you fill a room with steam and pass an electrical current through it... Does anything interesting happen?
Any electrons flowing through a superconductor will show up as a regular electric current.
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
The generator's voltage regulator will sense the fluctuation. If the voltage goes low more current will be applied to the armature to compensate. If the voltage goes high less current will be applied to the armature to compensate.
If the nail is iron and you pass an electric current through the wire then you have an electromagnet.
the water will be heated and electrolysed to give hydrogen and oxygen gases

The compass will align itself with the magnetic field generated by the current flow through the wires.
Hydrogen gas evolves from the cathode and oxygen gas evolves from the anode.
