v(s)=i(s)*r(s)

As a ohms law is V=IR we will ge the voltage as 4.8v option 4 is right.

V = IR.
V = (4*10^-6)(1.2*10^6).
V = (4*1.2)=4.8V.
V = (4*10^-6)(1.2*10^6).
V = (4*1.2)=4.8V.

@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.
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.

As we know from Ohms Law,
V = IR.
= (4*10^-6)*(1.2*10^6).
= 4.8v.
''Voltage = 4.8v''.
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.

How to calculate the resistance of voltage source?

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.
(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.
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.
