The battery and the negative pole of the power supply form a circuit
Purpose of the Power Supply Ground terminal?
I have a power supply with 3 terminals: "-", Ground and "+". Now I know that Ground is mains ground, but what does it mean? I thought that negative "-" terminal and Ground should be very near to each other. So I took voltmeter out and to my suprise the difference between the "-" terminal and Ground was zero, but the difference between "+" …

ground
First, analyze the circuit without the ground connection. There''s 6V from the battery across a total resistance of 450 ohm. So $$frac{6V}{450Omega}= 13.3mA$$ will flow trough the circuit. This means the 225 ohm resistor will have a voltage across it of $$13.3mA * 225 approx 3V$$ Thus, point C will be at 3V, relative to the battery''s …
