MT13-LMCT2: LOOPS WITH BULBS NEAR A CURRENT - BULB LIGHTING Two circular loops of wire with small bulbs in them are sitting beside two long straight current-carrying wires. The wire loops, bulbs, and long straight wires are identical for the two cases. The loops are the same distance from the straight wires. Case A Case B Bulb A Bulb B Current I Current , The currents in the long straight wires as a function of time are given in statements 1-6 below. For each of these situations, identify whether: (a) neither bulb is lit. (b) only bulb A is lit. (e) only bulb B is lit. (d) both bulbs are lit and equally bright. (e) both bulbs are lit, and bulb A is brighter. (1) both bulbs are lit, and bulb B is brighter. For each situation 1-6 below identify the effect from a-f above. 1) There is a constant current in wire A of 6 A (amperes) and in wire B of 15 A. 2) Both wires start with the same initial 3 A current, but the current in wire B increases to 6 A in a 0.3 second interval while that in A remains constant. 3) The current in wire A goes from 2 A to 10 A in a 0.5 second interval, while at the same time, the current in wire B goes from 12 A to 16 A. 4) The current in wire A decreases from 10 A to 4 A in a 0.2 second interval, while the current in wire B increases from 9 A to 18 A in 0.3 seconds. 5) The current in wires A and B both double in a 0.2 second interval, but the current in wire A starts at twice the initial value of B. 6) Both currents decrease from 32 A to 9 A, but the time interval for A is 0.5 seconds, while for B, the interval is 0.2 seconds.

Answer 1

From Faraday's low, Vinduced & Rate of change of flux V dt And we know that the flun is directly proportional to rate of change of corrent. 1.) (a) Neither bulb is lit ( Since there is change in current) 2) (C) Only bulb B is lit Case A А. 470 A ( Because current in case B changes but in current is constant. 3.) (e.) Both bulbs lit, but is brighter (since the sake of change of current in is high ) 4) (d) Both bulbs are lit and equally bright ( since sake of change of current is equal) 5.) (6.) Both bulbs are lit, but a A is brighter (Since rate of change of current in A is high) care B 6.) (f.) Both bulbs are lit, but B is brighter. (since rate of change of current in is greater) is
