Total resistance=3300ohms,And voltage 45 v.
If R3=1200 ohms and V=?
V=IR.
I=V/R => 45/3300.
I=3/220 A.
V=3/220*1200 =16.36.
V=16.36v.
If R3=1200 ohms and V=?
V=IR.
I=V/R => 45/3300.
I=3/220 A.
V=3/220*1200 =16.36.
V=16.36v.

3300 ohm --->45v.
1200 ohm ----> V2?
V2 = 1200*45/3300.
V2 = 16.3V.
1200 ohm ----> V2?
V2 = 1200*45/3300.
V2 = 16.3V.

V = 45V.
R = 3300 OHMS.
I = V/R.
I = 45/3300 = 0.013636363 A.
R3 = 1200 OHMS.
V3 = R3*I.
= 1200*0.01363636 = 16.36 VOLTS.
R = 3300 OHMS.
I = V/R.
I = 45/3300 = 0.013636363 A.
R3 = 1200 OHMS.
V3 = R3*I.
= 1200*0.01363636 = 16.36 VOLTS.

There is no block diagram of the circuit. Then how do we know that which one is R1, R2 or R3?

Given : Rtotal = 3300 ohms, V = 45V, R3 = 1200 ohms.
Required: Voltage across R3 = ?
Solution:
Itotal = V / Rtotal = 45/3300.
Itotal = 3/220 A.
Then,
V = IR3.
V = (3/220)(1200),
v = 16.36 V.
Required: Voltage across R3 = ?
Solution:
Itotal = V / Rtotal = 45/3300.
Itotal = 3/220 A.
Then,
V = IR3.
V = (3/220)(1200),
v = 16.36 V.

Use the equation of voltage devider.
vout = vin R3/(R1 + R2) + R3.
R3 = 1200 ohm.
R1 + R2 = Rt - R3.
vout = vin R3/(R1 + R2) + R3.
R3 = 1200 ohm.
R1 + R2 = Rt - R3.

Itotal=Vtotal/Rtotal
Itotal=45/3300
Itotal=0.0136
VR3=IR3*R3
VR3=0.0136*1200
VR3=16.32
Itotal=45/3300
Itotal=0.0136
VR3=IR3*R3
VR3=0.0136*1200
VR3=16.32

Total resistance = 3300 omhs.
Total voltage = 45 V
So,Total current = Total voltage/Total resistance.
Total current= 45/3300 => 0.0136 A
R3 = 1200 omhs
Voltage drop across it = I*R3
V3 = .0136*1200
V3 = 16.36 V (A answer)
Total voltage = 45 V
So,Total current = Total voltage/Total resistance.
Total current= 45/3300 => 0.0136 A
R3 = 1200 omhs
Voltage drop across it = I*R3
V3 = .0136*1200
V3 = 16.36 V (A answer)

Total resistance= 3300 ohms
Total voltage=45V
R3= 1200 ohms
V3= total voltage*R3/total resistance
V3=45*1200ohms/3300ohms
V3=16.36V
so option A is correct.
Total voltage=45V
R3= 1200 ohms
V3= total voltage*R3/total resistance
