Kirchhoff’s rules and Series and parallel resistors

(a) Write Kirchhoff’s loop rule for the circuit shown in Figure P16.27 for the case in which e₁ = 20 V, e₂ = 8 V, R₁ = 30 ?, R₂ = 20 ?, and R₃ = 10 ?. (b) Determine the current in the circuit. (c) Using this value of current, start at position A and move clockwise around the circuit, calculating the electric potential change across each element in the circuit (be sure to indicate the sign of each change). (d) Add these potential changes around the whole circuit. Explain your result.
