356901 The potential difference across the terminals of a battery is \(50\;\,V,\) when \(11\;\,A\) current is drawn and \(60\,\;V,\) when \(1\;\,A\) current is drawn. The emf and the internal resistance of the battery are

356902 A circular coil of radius \(R\) has a resistance of \(40\Omega \). Figure shows two points \(P\) and \(Q\) on the circumference separated by a distance \(\frac{{\pi R}}{2}\), which are connected to a 16\(V\) battery with internal resistance of \(0.5\Omega \). What is the value of current \(I\) flowing through the circuit?

356903 A current of 2 \(A\) flows through a \(2\Omega \) resistor when connected across a battery. The same battery supplies a current 0.5 \(A\) when connected across a \(9\Omega \) resistor. The internal resistance of the battery is

356904 A battery is charged at a potential of \(15\,\;V\) for \(8\,H\) when the current flowing is \(10\,\;A.\) The battery on discharge supplies a current of \(5\;\,A\) for \(15\,H.\) The mean terminal voltage during discharge is \(14\,\;V.\) The 'watt-hour' efficiency of the battery is
