An automatic electrical switch that breaks the circuit when excess current passes through it

As the switch S is closed in the circuit shown in figure, current passed through it is.

Does a conductor become charged when a current is passed through it?

When no current is passed through a conductor,

Write balanced and informative chemical equations for the following reactions. When electric current passes through water, it decomposes into hydrogen and oxygen.

shows three resistances are connected with switch S initially the switch is open. When the switch S is closed find the current passed through it.

An ac ammeter is used to measure currnet in a circuit. When a given direct current passes through the circuit. The ac ammeter reads 3 A. When another alternating current passes through the circuit, the ac ammeter reads 4A. Then find the reading of this ammeter (inA), if dc and ac flow through the circuit simultaneously.

How many coulombs of electricity are c onsumed when a 100mA current is passed through a solution of AgNO_(3) for half an hour during an electrolysis experiment?

The figure shows three circuits with identica batteries, inductors and resistances. Rank the circuits according to the currents through the battery just after the switch is closed, greatest fire

A dc ammeter and a hot wire ammeter are connected to a circuit in series. When a direct current is passed through circuit, the dc ammeter shows 6 A. When ac current flows through circuit, the ac ammeter shows 8A. What will be reading of each ammeter if dc and ac current flow simulataneously through the circuit?

Electric fuse is the strongest point in an electric circuit,which melts but does not break the circuit in case of faulty electric circuit.
