It can be as low as 1.5 volts. The B supply provides higher-voltage DC for the "plate" circuits of the radio. The B supply can be 22.5, 45, 67.5, or 90 volts.

Electric battery

OverviewTypesHistoryChemistry and principlesPerformance, capacity and dischargeLifespan and enduranceHazardsLegislation and regulation

Batteries are classified into primary and secondary forms: • Primary batteries are designed to be used until exhausted of energy then discarded. Their chemical reactions are generally not reversible, so they cannot be recharged. When the supply of reactants in the battery is exhausted, the battery stops producing current and is useless.
