B. In an electric circuit, electron flow a from of point of ________ potential to the point of ____________ potential.

C. The differences between the electrostatic potential of the positive end the negative end of an electric cell is the __________ of the cell.

D. Three electric cells of potential difference 1.5 V each have been connected as a battery. The potential differences of the battery will be ________ V.

E. An electric current flowing in a wire creates __________ around the wire.

Answer 1

A. Water in the waterfall flows from a higher level to the lower level because of potential differences.

B. In an electric circuit, electron flow a from of point of higher potential to the point of lower potential.

C. The differences between the electrostatic potential of the positive end the negative end of an electric cell is the potential of the cell.

D. Three electric cells of potential difference 1.5 V each have been connected as a battery. The potential differences of the battery will be 1.5 + 1.5 + 1.5 = 4.5 V.

E. An electric current flowing in a wire creates magnetic field around the wire.
