QNEET-2024-Ph-151: NEET 2024 Physics - Class 11 NEET-2024-Ph-151 Solution: In an electrical circuit the voltage is measured as \(V=(200…

To determine the resistance R using Ohm's law, we use the formula: R = V I Given: V = ( 200 � 4 ) volts I = ( 20 � 0.2 ) amperes First, calculate the nominal value of the resistance: R = 200 20 = 10 � Next, we need to calculate the uncertainty in the resistance. For division, the relative uncertainties add up. The relative uncertainty for voltage is: _ V V = 4 200 = 0.02 and for current: _ I I = 0.2 20 = 0.01 Adding these relative uncertainties gives us the relative uncertainty for the resistance: _ R R = _ V V + _ I I = 0.02 + 0.01 = 0.03 Now, we calculate the absolute uncertainty for the resistance: _ R = R _ 0.03 = 10 _ 0.03 = 0.3 � Therefore, the resistance with its uncertainty is: R = 10 � 0.3 � Thus, the correct answer is: Option B ( 10 � 0.3 ) �
