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. That being said, the maximum current you can safely draw from a battery is often related to its capacity (see C ratings), but this varies battery to battery

Despite the lack of voltage output, there is still a current flowing through the circuit. This is due to the small amount of resistance in the shorting wire and the overall voltage being determined by the source EMF of the battery or power supply.

Current flow in batteries?

In your battery example, there is no return current path so no current will flow. There is obviously a more deep physics reason for why this works but as the question asked for a simple answer I''ll skip the math, google Maxwell''s Equations and how they are used in the derivation of Kirchhoff''s voltage law. Batteries do make a good example for this simply

Panels with Voltage but no Current | DIY Solar Power Forum

1. Disconnected 2 of the panels and only connected 1 to the MPPT controller. Voltage dropped to 35v but still no current. Also plugged the single directly into the wires to the MPPT (bypassing the parallel connectors). Same behavior - voltage, no current. I know the cables to the MPPT work from the other 3S array, and those are plugged directly

Battery is good but no power to anything

2009 - 2014 Ford F150 - Battery is good but no power to anything - 2013 F-150 with 5.0 V8: The truck acts as if the battery was completely dead: dash does not come on with key on, door locks do not work, power anything does not work. I checked the battery with a multimeter and it shows 12V. I checked voltage between...

Solar Panels Have Volts but No Amps: Reasons and Fixes

Let''s say you have one small voltage and one big voltage. Current will flow from Big Voltage to Small Voltage. Now the current flows properly in a good circuit. Here comes the open circuit. Where your circuit is not properly configured and is incomplete. Here our current has no way to flow properly and you have zero amps despite having voltage.

Then We can no longer ignore Rs in the current equation. Let''s take the extreme case that RL is much smaller than Rs. Then we can ignore RL in the current equation, and we get $$ I = frac{V_o}{R_s} $$ This is the

Car Battery Has Voltage But No Amps [5 Easy Fixes]

The main reasons behind a car battery has voltage but no amps are a dying battery, bad contact between rectifier and load, loose connection, malfunctioning battery cell, and high resistance. You''d have to replace the battery to solve this problem in most cases.

Can A Battery Have Voltage But No Current? Easy

The primary troubleshooting steps you should take if a battery shows voltage but no current include checking connections, testing with a load, measuring internal resistance, and inspecting for corrosion.
