Expert Answer:
Electric wires are at very high potential and ground is at zero potential i.e. current will flow through the wire from higher potential to lower potential. Which shows there is potential difference. So, when a bird is sitting on such a wire, its whole body is only at a higher potential. Hence,there is no potential difference occurs. Due to the absence of a lower potential, the current will not flow through them and birds sitting on a electric wire not get shock.

- why does need to maintain the current in a given electric circuit by expanding its energy stored in it?
- The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
- If charge on one electron is 1.6 x 10 -19 C. Calculate number of electrons required to constitute 1A of current in 1s.

- The MCB of a Rupa’s room is tripped and keeps on tripping again and again. If it is a domestic circuit, what could be the reason of this phenomenon?
- a current
- if 20 C of charge pass a point in a circuit in 1 second what current is flowing
- an electric bulb is related220 V and 100 W when it is operated on 110 V the power consumed will be
- A coil draws a current of 1.0 ampere and a power of 100 watt from an A.C. source of 110 volt and 5√22/π hertz. Find the inductance and resistance of the coil.
Why can't I use P=VI here, and how can I determine when to use P=VI or P=I^2 R or P=V^2 / R
