A.C and D.C have the same:

Explanation

The correct option is Effect in charging battery. Both AC and DC can charge a battery, but typically AC is converted to DC for this purpose. The important factor is that the charging mechanism manages the voltage and current appropriately. While AC and DC currents have different characteristics, the end result of charging the battery-restoring its stored energy-can be achieved with both, given the right conditions.Option B is incorrect because capacitors react differently to AC and DC; they charge and discharge continuously with AC. Option C is incorrect because while both AC and DC cause heating, the effect depends on how the AC is measured (RMS value). Option D is incorrect as inductances behave differently under AC, where they induce a current due to the changing magnetic field, unlike the constant field from DC.
