Battery parallel power supply internal resistance
When the battery''s internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V.

Why is it Important to Measure Battery''s Internal Resistance?
When the battery''s internal resistance, R DC, is 1 Ω, and the load, R, is 9 Ω, the battery outputs a voltage of 9 V. However, if the internal resistance increases to 2 Ω, the output voltage drops to approximately 8.2 V.

Different voltage sources in parallel
Some power supplies really don''t like to be connected in parallel however so check the manual, or with the manufacturer first. For example a crowbar circuit on the output of one power supply, for OVP, may cause very high currents to flow possibly resulting in the failure of one or both power supplies.
