Q. In the given circuit, calculate the potential differences across each resistor
Solution :
i) Rs = R1 + R2 + R3 = 10Ω
ii) Current in circuit I = V/Rs = 10 / 10 = 1 A
iii) Voltage drop across R1, V1 = IR1 = 1 × 5 = 5V
Voltage drop across R2, V2 = IR2 = 1 × 3 = 3V
Voltage drop across R3, V3 = IR3 = 1 × 2 = 2V
Minimum amount of light for low vision If 90 photons enter the eye ,10 or less are actually absorbed in photoreceptors. About 3% are reflected at the surface of the corne
Magnification is the ratio of size of image to the size of object. hence it is a dimensionless constant. It has no units. 1/m is not its unit.(1/m is the unit of power=DIOPTRE)
