Two resistors a and b are connected in parallel to a 12-v battery. resistor A has 9 V across it. which resistor has the least resistance? If i am discharging a capacitor of tension Uc in a resistance R,in my book they say that Uc+Ri=0
can you say why it is not Uc=Ri? Die design with latest technologies? Write down the cube roots of unity in the form a + ib where a,b,∈ R and i = √−1. Hence, or otherwise show that

A -202
B -181
C -91
D 72
E 346?
