The EMF of the current source is equal to 120V, what work is done by external forces when the 19C charge moves inside the source from one pole to another.
Initial data: ε (EMF in the considered current source) = 120 V; q (the value of the charge, which is moved by external forces) = 19 C.
The work that will be done by external forces when the charge moves inside the source under consideration, we define by the formula: Ast. = ε * q.
Calculation: Ast. = 120 * 19 = 2,280 J.
Answer: To move the charge from one pole of the source to the other, external forces performed work of 2,280 J.
