Question

I just need an explanation, how do you solve this problem? what formula or law you use to compare the brightness of two bulbs?

Problem Po Two circular loops of wire withsmall light bulbs in them are sitting beside two long straight current carrying wires. Everything is identical for the two cases except, possibly the currents in the long straight wire. Answer the six questions below that describe situations with di long straight wires. Check all boxes that apply. If both bulbs are lt fill in the last colu Case A Case B Current / Current! Bulb A Bulb B BulbBulb Which is brighter A is lit B is lit (or write same", if they are the same brightness 1) Both wires start with the same initial 3 A current, but the current in wire B increases to 6 A in 0.3 s, while that in wire A remains constant 2) There is a constant current in wire A of 6 A and in wire B of 15 A 3) The current in wire A goes from 2 A to 10 A in 0.5 s, while at the same time, the current in wire B goes from 12 A to 16 A 4) Both currents decrease from 32 A to 9 A, but the time interval for A is 0.5 s, while for B is 0.2 s 5) The currents in wires A and B both double in 0.2 s, but the current in wire A starts at twice the initial value of B 6) The current in wire A decreases from 10 A to 4 A 0.2 s, while the current in wire B increases from 9 A tn 18 A in 0.3 s he
