When an animal touches an .electric-fence. the ani mal gets a shock by completing an electrical circuit.How much charge passes through the animal, if it receives a current pulse of 20mA for 0.1 seconds.

When an animal touches an .electric-fence. the ani mal gets a shock by completing an electrical circuit.When a bird perches on the electric fence, the bird will not get a shock. Why?

0.5 A current flows through an electric heating device connected to 230 V supply . The quantity of charge that flows through the circuit in 5 minute is

"When electric current is passed through a resis tance wire, it get heated up" . Name the law associated with this phenomenon.

0.5 A current flows through an electric heating device connected to 230 V supply . How much is the resistance of the circuit ?

When electric current is passed through a resis tance wire, it get heated up" What happens to the heat energy developed, if the current through the wire is doubled.

A point charge causes an electric flux of -1.0xx10^3Nm^2//C to pass through a spherical Gaussian surface of 10.0 cm radius centred on the charge. If the radius of the Gaussian surface were double, how much flux would pass through the surface ?
