For a circuit find the total potential differences if two resistors of resistance R1 and R2 respectively kept series wise for a
current I passing through it.

-- If the two resistors are connected in series, then they behave like a single resistor whose resistance is (R₁ + R₂) ohms.

-- For any resistance, the potential difference (volts) across the resistance is   V = (current) x (resistance) .

-- So in THIS circuit,  V = I x (R₁ + R₂) .
