WhatsAppStandard car batteries are listed as 12-volt batteries. However, this is rounding down, as a car battery should have a "resting voltage" – which is to say, the amount of voltage it has when it''s turned off – of 12.6 volts.
WhatsAppThe voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or loaded down. However, if the device''s output voltage can be measured without drawing current, then output voltage will equal emf (even for a very depleted battery).
WhatsAppLarge voltage at zero current! Blasphemy!!! So, if voltage isn''t caused by current, what then causes voltage?
