Electric Current Exam1 and Solutions; Electric Current Exam2 and Solutions ; Next >Electric Current Exam1 and Problem Solutions; Additional Information . R is the resistance in ohms and controls the flow of electric current. We have the circuit on the right, with a driving voltage US = 5 V, and we want to know U and I. a. R = 1000 Ω; the total resistance in the circuit is then Rtot = 1010 Ω, and we can use Ohm's law to find I = U S/R tot = 5/1010 A = 4.95 mA and U = RI = 4.95 V. b. Question TitleCircuit Problems I Which direction do both the conventional current and the ... and defined electric current as flowing from a positive terminal to a negative one (counterclockwise in the diagram). Circuits. The charge carriers could be electrons in a vacuum, electrons in a metal, 'holes' in a semiconductor or ions in a solution. The drift velocity is very small !

Electric Current Exams and Problem Solutions. After Alessandro Volta invented the voltaic pile which was later known as Battery, electric current came much into picture.It used chemical reactions to create an electric potential difference between two different metals which are known as Electrodes.When two electrodes were connected together, current began to flow.

The magnitude of the electric field at point A is 36 N/C. Units of ρ are Ω ⋅ m . From the phasor diagram, we readily see that both the current and the voltage are in phase with each other.
