In which case an electromotive force is consuming electrical energy from the electrical circuit?
14 In which case an electromotive force is consuming electrical energy from the electrical circuit? Electromotive force is always consuming electrical energy from the electrical circuit. When the electrical current is passing through the electromotive force from its negative to positive terminals. Electromotive force is always producing electrical energy to the electrical circuit. When the electrical current is passing through the electromotive force from its positive to negative terminals.15.
