Hi guys,

On the picture you see a circuit. The Voltage between the four 330 Ohm resistors must be 0 V. I draw it in this picture. When there is no Voltage i have no ampere between the 100K Ohm potentiometer and the first Dot between the two 330 Ohm resistor or ? I mean the ampere measurement with the red "" ?1 "" Symbol.

Is my calculation right?

U1 = 330 Ohm * 0,02A = 6,6V

U2 = 330 Ohm * 0,02A = 6,6V

U3 = 330 Ohm * 0,02A = 6,6V

U4 = 330 Ohm * 0,02A = 6,6V

U1,2= 6,6V+6,6V ? 13,2V

U3,4= 6,6V+6,6V ? 13,2V

U = 13,2V

My calculation for the second Question Symbol"" ?2 ""

I=U/R = 13,2V / 100000Ohm = 1,32*10^-4 A= 0,132 mA

( I ) for the circuit is then:

I = U/R = 13,2V / 328,9 Ohm = 0,04 A

Is my calculation right, or did I make a big mistake?
