Quick question Voltage

[mikali]

I just need to confirm some things about voltage and current. Dont need to work out the problems, just the concepts, or what you would do to solve.

Problem 1) Circuit 3 Picture

The problem has multiple resistors in parallel, I know voltage is the same for resistors in parallel. Could I either find the voltage at the 16ohm resistor multiplied by I1=1A and use this value. Or should I reduce the circuit and find an equivalent resistor

Problem 2) Circuit 4 Picture

Need to find the value of R, if the Resistor Equivalence is 4 ohm. It seems that R and 2 ohm are in parallel, and the 5 and 6 ohm resistors are in series which are in parallel to the R and 2. And this is in series with the 1 ohm. Or should I use a Y-Delta Transform. Which do you think would be the easiest way?

Yes.

R and 2 ohm are in parallel

Yes.

the 5 and 6 ohm resistors are in series which are in parallel to the R and 2

No. Redraw the circuit like this:
