PH 2223 Test III-A April 15, 2002 Name:_____________________________________________Column:_______________ Darken the [ ± ] of the letter of the correct answer. To have a chance for partial credit you must hand in well-organized scratch paper on which work is clearly shown. Staple the scratch paper to the back of this test . eo Constants: m = 9.109×10 kg , e = 1.602×10 C , : = 4 B × Tm/A - 31 - 19 - 7 Use the circuit diagram at right for the next three problems. 1. With the assumed directions, which equation correctly relates the 123 213 312 three currents? [a] I = I + I [b] I = I + I [c] I = I + I 2. What is the correct Kirchhoff voltage equation for the outside loop involving two 8 S resistors and two batteries? 13 [a] 12v - 8 S I + 8 S I - 9v = 0 [b] 12v - 8 S 8 S + 9v = 0 [c] 12v - 8 S - 8 S - 9v = 0 [d] 12v - 8 S 8 S + 9v = 0 [e] 12v + 8 S 8 S - 9v = 0 [f] 12v + 8 S 8 S + 9v = 0 3. Keeping in mind that the assumed direction may or may not be 2 correct, what is the magnitude and direction of current I ? [a] 3/16 A right [b] 3/16 A left [c] 7/16 A right [d] 7/16 A left [e] 15/16 A right [f] 15/16 A left [g] 21/16 A right [h] 21/16 A left [i] 29/16 A right [j] 29/16 A left 4. In the circuit at right, if the current is 4 A in the 4 S resistor, what is the current in the 1 S resistor? [a] 1/4 A [b] 1/ 2 A [c] 1 A [d] 2 A [e] 4 A [f] 6 A [g] 8 A [h] 16 A [i] 32 A [j] 64 A 5. In the circuit directly below this question, if the voltage across the 4 S
