A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.

Electricity needs a path to pass from the positive terminal to the negative terminal of an electric cell. A connection that provides a path outside an electric cell, for the electricity to pass from the positive terminal to the negative terminal of the cell, is called an electrical circuit.
If the electric circuit is broken i.e. If the electric current is not flown in the electric crcuit, the circuit is said to be an open electric circuit.
