Unformatted text preview: Hint: You may fnd it helpFul to work out the currents through the bulbs For the case V = 1 V , and R = 1 Ω For all the bulbs, then compare the currents. 1. A = B = C = D = E 2. E = D > A > B = C 3. A = B > C > D = E 4. A = D = E > B > C 5. B = C > A = D = E 6. A = B = C > D > E 7. C > B > A > D > E 8. A = C > B > D = E 9. A = B = C > D = E 10. A = D = E > B = C correct Explanation: ²rom the fgure, with all the bulbs having the resistance R , I A = I D = I E = V R I B = I C = V 2 R Version 089/ABBCB – QTest #5 – Antoniewicz – (56495) 2 The rankings of the currents shown here are also the corresponding rankings of the bright-ness....
