Question

?

Answer 1

d) any attempts so far? it's pretty much like the picture in g except without the switch and resistor C

Answer 2

something like that

anyway for e) what's the resistance for two resistors (3 and 6) in series?

Answer 3

i would do 3 and 6 so it would be

Answer 4

do you remember what the rule is for resistors in series?

Answer 5

oh okay, yeah I forgot about that

Answer 6

so 3^2+6^2

Answer 7

you just add them, you don't have to square them

Answer 8

3 + 6 = 9 ohms = your sol'n

Answer 9

wait wait wait

Answer 10

they're in parallel whoops

Answer 11

so 1/T = 1/3 + 1/6 solve for T

Answer 12

t=2?

Answer 13

good so total resistance = 2ohms

Answer 14

anyway for f) we kind of touched on this yesterday but it's a piece of metal that melts when the current becomes too high, opening the circuit

Answer 15

for g) which resistor(s) stop working when the switch is opened?

Answer 16

All of them

Answer 17

well done
