List of top Physics Questions on Current electricity asked in AP EAPCET

According to Ohm's law, the relation between the electric current $I$ and the potential difference $V$ across a conductor is

The quantities that don't change when a resistor connected to a battery is heated due to the current are:
(A) Drift speed (B) Resistivity (C) Resistance (D) Number of free electrons

A battery with a \(12\,\text{V}\) emf has an initial charge of \(80\,\text{A h}\). If the potential across the terminals stays constant until battery is completely discharged, then this battery can deliver energy at the rate of \(120\,\text{W}\) for a time:

A battery of emf \(12\,\text{V}\) and internal resistance \(4\,\Omega\) is connected to a resistor. The resistance of the resistor if the current in the circuit is \(0.8\,\text{A}\) is
