If resistors are connected in series,the current through each resistor remains the same.

$A$ battery is a source of maintaining a constant potential difference across two ends of a conductor.

Two resistors of $3 \Omega$ and $6 \Omega$ are connected in parallel. The equivalent resistance $R$ is:

Name and define the $SI$ unit of resistance. Calculate the resistance of a resistor if the current flowing through it is $200\, mA$, when the applied potential difference is $0.8\, V$.

State $Ohm's$ law. Calculate the resistance of a conductor,if the current flowing through it is $0.2 \, A$ when the applied potential difference is $0.8 \, V$.

According to Ohm's law,which of the following statements is correct?
