1 71 R2 R3 2 T2

Consider the circuit pictured.

a. Write down the ’loop rule’ for the top and bottom loops of this circuit assuming you go around the loops clockwise.

b. Write down the ’junction rule’ for the two junctions in the circuit.

c. Determine the current and potential difference across each resistor for the following values: R1 = 1.00 ?, R2 = 2.00 ?, R3 = 3.00 ?, r1 = 1.00 × 10?1 ?, r2 = 1.00 × 10?1 ?, E1 = 1.00 × 101 V, E2 = 1.00 × 101 V.

Answer 1

a) Kirchhoff's loop rule states that the sum of the emf values in any closed loop is equal to the sum of the potential drops in that loop.
    Kirchhoff's loop rule is a rule pertaining to circuits that is based upon the principle of conservation of energy.

​Mathematically, Kirchoff's loop rule can be represented as the sum of voltages (V_k) in a circuit, which is equated with $\sum$ V=  0.
b) Kirchhoff's junction rule 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.

Kirchhoff's junction rule is an application of the principle of conservation of electric charge: current is flow of charge per time, and if current is constant, that which flows into a point in a circuit must equal that which flows out of it.
