1. A bird sitting on a high power electric line
is still safe. How?
2. Does a solar cell always maintain the
potential across its terminals constant?
Discuss.
3. Can electroplating be possible with
alternating current?
Answers
Answer:
No moving electrons means no electric current. Our bird is safe, for the moment anyway… If that bird stretches out a wing or a leg and touches a second wire, especially one with a different electrical potential, it will open a path for the electrons — right through the bird's body.
Explanation:
Birds can sit on the power line and does not get electrical shop because electricity is always looking for a way to get the ground the current is not flowing out of its body to any other materials current flows in a loop when which means the which means the circuit is close and your bird sitting on a transmission line does not complete the circuit if the same but keeps on one leg on one line and another leg on any part of its body on the another line are the neutral points then it will get burn
2) solar cell delivers constant current for any given illuminating level while the what age is determined by the load resistance potential in the solar cells depends on the intensity of the solar radiation since the intensity of the solar radiation is not always constant the potential across its terminal not constant
3) heating effect on the chemical effect of experiments have to be performed only with the DCcell around 9 volt dc cell will not give any electric shock to any cost should not use the main domestic electrical supply which is 220 volt if its use it will give a heavy shock leading to the severe damage to our body
