Chapter 3: Current Electricity - Assertion-Reason Quiz

Assertion (A): Cells are preferred in series when a higher terminal voltage is required, while cells in parallel are preferred when a higher current or lower internal resistance is needed. Reason (R): Series combination adds EMFs and internal resistances; parallel combination reduces effective internal resistance and averages the EMF, enabling larger currents without large voltage drops.
