# Circuit with voltage source, resistance and current source

Suppose I have a (closed) circuit with a voltage source $V$, a resistance $R$ and a current source $I$ (in this order). Is it true that the voltage across the current source is $V-RI$ ?

• Could you provide the values (just out of curiousity)? – heather Jul 12 '16 at 23:25
• I don't have any values – user72870 Jul 12 '16 at 23:27
• yes is true, is all you wanted to know? – Wolphram jonny Jul 12 '16 at 23:36
• Although not stated, I assume you mean the circuit elements are series connected and then the answer depends on one's choice of reference polarity (for each voltage variable) and reference direction (for the series current variable). In other words, draw a circuit diagram appropriately labeled. – Alfred Centauri Jul 13 '16 at 1:49
• Could also be V+RI, it depends on the direction of the voltage source and the current. – Previous Jul 13 '16 at 6:40
