ELECTRIC CURRENT AND ITS EFFECT

The arrangement where an electric current flows in a conductor when it is connected to a source of electric current is known as

• electrical energy

• elements of a circuit

• conducting wires

• electric circuit

what are the elements of a circuit?

• bulb

• wires

• cells

• batteries

• switches

Electric current has energy called

• potential difference

• thermal energy

• electrical energy

• light energy

copper wires are used as conducting wires. because

• it offers no resistance

• it offers very high resistance

• very cheap in price and easily available

• it offers very less resistance

Filament of a bulb is made up of............because it offers very high resistance.

• copper

• silver

• iron

• tungsten

The greater the resistance offered by the wire to the flow of current, the ...................would be the heat generated.

• lesser

• smaller

• greater

which effect of current is used in an electric fuse?

• lightning effect

• insulating effect

• flowing effect

• heating effect

Which are not the effect of an electric current?

• heating effect

• lightning effect

• magnetic effect

• electrical effect

The switch that automatically stops the current in a circuit if the current exceeds the specified limit, is knows as

• FUSE

• SWITCH

• MCB

• SHORT CIRCUIT

The fuse wire is made up of an ...............with ............melting point.

• alloy, low

• copper, low

• semiconductor, high

• silver, high
