Two Circuits, physics?

Question

Consider the sections of two circuits illustrated above. Select True or False for all statements. Rab (parallel circuits) Rcd( series)
1. After connecting c and d to a battery, the current through R3 always equals the current through R4.
2. Rcd is always less than or equal to R3.
3. Rab is always less than or equal to R1.
4. After connecting a and b to a battery, the voltage across R1 always equals the voltage across R2.

Answer 1

It might help just a -tiny- bit if we could actually see those circuits ☺

Answer 2

ok well i really cant do any thing with this but R3 and R4 are resistors most likely. resistors are usually represented on a diagram with a VVVV not real vs but i line like that. and to read risistors you have black=0 brown=1 red=2 orange=3 yellow=4 green=5 blue=6 violet=7 gray=8 white=9
the first line is the first number
the second line is the second number
and the third is the number of zeros after
so lets say it is red green blue
the resistance would be 25,000,000 Ω
and the formula for Watts is
I = V x R
or you may have see it as
current = volts x ohm
or
amperes = volts X ohms
ok
i hope that helps

Answer 3

sixteen. A. because it particularly is a parallel circuit subsequently all aspects are straight away linked to the provision. So if some aspects are bumped off/flow out different aspects will stay linked to the provision subsequently stay on. 17. C. because it particularly is an occasion of a sequence circuit. In a sequence circuit any wreck everywhere will result interior the circuit being broken. so all aspects wont acquire ability. subsequently will flow turn off.

Answer 4

I agree.
