Several factors can cause voltage but no current. Possible causes are: 1. Open Circuit Cause: A break or disconnection in the circuit. Solution: Check for loose or disconnected wires, damaged components, or switches that are not closed. Repair or replace any faulty elements to complete the circuit. 2. Faulty Components
To answer will it provide current to the load depends on the particular load in question. If the load is just sipping a tiny amount of current, then the answer is probably yes. But there is no guarantee. Mar 8, 2020 at 7:51 The voltage decrease over time varies from battery to battery.
To resolve the issue of getting voltage but no amps check for open circuits. Another reason for zero amps could be incorrect measurement techniques, such as connecting a multimeter in parallel and blowing its fuse. Verify correct connections, measure resistance, test components, and ensure power supply compatibility to solve this problem.
It only determines how long the battery can supply a current for (that is, how much energy is can output over a period of time). The max current is determined by it's internal resistance. Many 4.2V lipo batteries can supply much more current than 9V batteries since they tend have lower internal resistances.
