QUESTION 30 A student has to calculate the currents in the circuit shown in the diagram. After he chooses the current directions and applies Kirchhoff’s Junction Rule, he applies Kirchhoff’s Loop Rule to loop A (clockwise), as shown in the diagram. Which of the following is a correct equation for this loop? 402 w 11 A 1 B 31 312 212 O +3 – 4 +312-214 = 0 +3 – 4 – 312 +211 = 0 0-3 +4 – 312 +214 = 0 +3 +4 +312-211 = 0 QUESTION 26 How much current flows through the resistor in the diagram? W V 20 V 3V v O2V/R O 3V/R OV/R O 4V/R
