If a current of 3 A goes out of a junction the sum of all the currents going into the junction equals 2 A. true or false
Homework Answers
Ans: False.
According to Kirchhoff's junction rule which states that at any junction ( node ) in an electrical circuit, the sum of the currents flowing into that junction is equal to the sum of the currents flowing out of that junction.
The sum of the currents into a junction equals the sum of the currents out of...

Kirchoff’s First Rule, or Junction Theorem, states that = the sum of currents at any junction is the resultant current = the algebraic sum of voltages around a closed loop is zero = the algebraic sum of the currents at any junction is zero = the algebraic sum of voltages is the resultant voltage

Remember that the current coming into a junction equals the current coming out of the junction. Also bear in mind that voltage is basically a height difference between two points. 1) If you measure the potential across two batteries and find that V1 = 1.3V and V2 = 1.4V, then you measure the potential between the negative ends of battery 1 and positive end of battery 2 and get V12-+ = -0.1 and the potential between the positive ends of...

Kirchoff's voltage rule states that: O A The algebraic sum of the change in potential in a complete transversal of a loop in a circuit must be zero. B. The product of current and resistance is the voltage. OC. The algebraic sum of the currents entering a junction equals the algebraic sum of the currents leaving the junction OD. The algebraic sum of all the resistance in a circuit is zero,

Which among the following statements is CORRECT? A) The junction rule says that the sum of the currents entering any junction must equal the sum of the currents leaving that junction. B) In a series circuit, the resistors all have the same electric potential difference. C) The direction of the magnetic force on a charged particle moving in a magnetic field is always in the same plane as the velocity and magnetic field vectors. D) Faraday's law states that induced...
