Given data:-

I = 4 micro Amps.

R = 1.2 Mega Ohms.

V = IR.

So, V = 4*1.2 = 4.8 V.

(where micro & mega is cancel out, because micro means 10 the power minus -6 & mega means 10 the power plus +6).

I = 4 micro Amps.

R = 1.2 Mega Ohms.

V = IR.
So, V = 4*1.2 = 4.8 V.
in options 2nd is the resistance so, by using this vtg we can find r=4.8/4*10^-6=1.2 Mohm.

Using Source Conversion Theorems.

Current Source Converted to Voltage Source - Vs = Is*Rs=4*1.2 = 4.8V.

Now Rs = 1.2Mohm Connected Series with Voltage source.

@Sabari @Bharat @Janmejay your procedure is not correct.

P = VI = V^2/R = I^2*R.

P = 4.8^2/1.2*10^6 = 1.92*10^-5.

So option D is correct.

This is a case.

Convert current source to voltage source.
So voltage is 4.8 & resistance is no change.

Apply Ohm's law to find voltage.

And there will be no change in resistance.
V=IR,
V=4.8V,
R=1.2Mohms.

As we know from Ohms Law,

V = IR.

= (4*10^-6)*(1.2*10^6).

= 4.8v.

''Voltage = 4.8v''.

There are two options with 4.8v so by calculating power we can get right option.

Bharat said:   1 decade ago
As a ohms law is V=IR we will ge the voltage as 4.8v option 4 is right.

Sabari said:   1 decade ago
V = IR.

V = (4*10^-6)(1.2*10^6).

V = (4*1.2)=4.8V.
