Question

a) Find the equivalent resistance, in ohms, between points a and b for the circuit shown in the figure. (R1= 5.10 ?,R2= 4.40 ?,R3= 5.60 ?,R4= 8.10 ?)

I got 15.65 for this which was correct.

This is what I am having difficulties with.

b) Calculate the current, in amps, in resistor R2 if a potential difference of 35.0 V is applied between point a and b for the circuit shown in the figure.

This is what I am having difficulties with. Calculate the current, in amps, in resistor R2 if a potential difference of 35.0 V is applied between point a and b for the circuit shown in the figure.

Explanation / Answer

b)total i=35/15.65=2.2364amp

current in r2= (5.6/(5.6+4.4))*2.2364=1.25amp
