Question

Determine the voltage which must be applied to a 1 k 2 resistor in order that a current of

Answer 1

Answer:

The correct solution is "20 volt".

Explanation:

Given that:

Current,

I = 10 mA

or,

 = $10\times 10^{-3} \ A$

Resistance,

R = 2 K ohm

or,

  = $1\times 10^3 \ ohm$

Now,

The voltage will be:

⇒ $V=IR$

By putting the values, we get

        $=10\times 10^{-3}\times 2\times 10^{3}$

        $= 20 \ volt$
