`10^(20)` electrons, each having a charge of `1.6xx10^(-19) C, pass from a point A towards another point B in 0.1 s. What is the current in ampere ? What is its direction ?

One billion electrons pass from a point P towards another point Q in 10^(-3) s. What is the current in ampere ? What is its direction ?

In a conductor, 10^(16) electrons move from a point A towards point B in 1 milli second. 10^(14) positive ions move from a point B towards point A in 1 milli second. What is the current in ampere and its direction? Charge on electron = charge on position ion = 1.6 xx 10^(-19)C .

An electron carrying a charge of 1.6xx10^(-19)C revolves in a circle at 10^(16) revolutions per second. The equivalent current is
