Hi guys, I have a question... If volts are 50 and one resistence is 5mA, what is the value of the other resistence?

Thanks in advance..

    You'll have to be a little less ambiguous in your question. "One resistance is 5mA ... the other resistance" doesn't mean anything.

    Also, a quantity with units of Amperes (i.e. 5mA) is not a resistance but a current. Resistance has units of ohms (Ω). So, assuming that you're referring to a simple circuit with a voltage supply connected to a single resistor, then the resistance is defined as the voltage divided by current:

    R = V/I

    In your case, 50 V / 5 mA = 10 kΩ
