Question

R1 is 150 ohms, and R2 is 220 ohms. (150 +220 = 370). In a series circuit, the current is the same across the circuit.  The available power storage is 6 volts.  The problem I am have is conceptualizing what V1 + V2 equals.  I conjecture that the sum would be less than 6 V.  I can't say 3 + 3 =6 V, but rather V1 + V2 < 6?

Unless R1=R2, then perhaps 3 + 3 = 6V.  However, R1 is 150 ohms, and R2 is 220 ohms.

Complicating issue, if I use an ammeter and voltmeter, these devices may have some internal resistance, so equals becomes < 6 V?

How then do I conceptualize better, V1 + V2, so that maybe it is based on the value of the individual Resistor?
