I have a resistor connected to a power supply that delivers a fixed voltage for any current (up to some maximum current). With a multimeter, I find that the resistance of the resistor is 50 Ohm resistor and that the current flowing through it is 0.2A. What is the voltage of this power supply?

Respuesta :

Answer: 10 volt

Explanation:

We know by Ohm's law: V=IR

Here,

I = 0.2 A

R = 50 ohm

Then,

V= 50*0.2 =10 volt.

Note: voltage not change in series circuit.

So, The Supply voltage is 10V.
