1. Calculate current and voltage difference for each resistor and fill the table.
V=I*R
V1V2V3V4V5V6
8/12*15=10 13/20*15=9.75v 7/20*15=5.25 5/2.5*7.5=15v 5/2.5*7.5=15v V6=7.5v

a. What is the total resistance of the circuit?Req=12k OHM
b. If R5 is is short-circuited, how R1 and R3 is affected? Evalute their current and voltage
difference changes.V1 same while V1same while i1 incrase as the total resistance decrease
V3 and i3 will by the same
c. If R5 is is short-circuited, how R1 and R3 is affected? Evalute their current and voltage
difference changes. V1 same while incrase as the total resistance decrease
d. Are there resistors of the same current value? Why? Yes R2 and R3 . decause they conneced
In series
e. Are there resistors of the same voltage difference value? Why? Yes R4 and R5 because they
are connected in parallel with the batterey
