Can anyone help me to understand the basic thing. I want to know how much will be the voltage on the anode of diode D1 in case if we assume that on D1cathode we have -14v as it is on diagram. As i understand in this condition diode is forward biased and it will conduct the current. But what about the voltage on point of anode? The resistor values must be taken into account also. My main concern is if it will be positive relative to 0V or negative. Thanks
