Why is there a voltage drop across things when no current is

If you have an electric circuit with a 12V battery in series with an open switch and a resistor, the voltage drop across the open switch is 12V. But this doesn''t quite make sense to me. If there is no current, why does Ohm''s Law not apply giving me a voltage drop of V = IR = 0 as there is no current? I guess more generally I''m confused as to why things with zero current

6 FAQs about [The voltage is normal but the battery has no current]

Does a battery have a voltage vs current?

Key Takeaways Voltage vs. Current: Voltage can be present in a battery without significant current (amps). Battery Health Indicators: Voltage alone is not a reliable indicator of a battery’s ability to deliver power. Internal Resistance: High internal resistance can lead to a situation where a battery shows voltage but no current.

Why does my car battery have volts but no amps?

Another common reason behind a car battery having volts but no amps are bad contact somewhere between the rectifier and the load of the battery. You need to between the load and the anode bar to know if this is the case. If you see a drop in voltage when testing it, you can confirm that there’s a bad connection.

Can a battery have voltage without significant amperage?

In wrapping up, it’s clear that a battery can have voltage without significant amperage. This phenomenon often signals issues like high internal resistance or battery wear. Understanding this concept is not just about satisfying curiosity; it’s crucial for ensuring the reliability and safety of the devices we depend on daily.

What causes voltage but no current?

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

What does voltage but no amps mean?

Simply said, it signifies that your circuit is incomplete or defective. The causes of this problem are using the incorrect voltage, making the incorrect connection, and having problems with the panels or solar charge controller. To resolve the issue of getting voltage but no amps check for open circuits.

Why do batteries have a low amperage?

It’s the opposition within the battery to the flow of current. As batteries age or undergo multiple charge-discharge cycles, their internal resistance increases. This increase can lead to a situation where, despite showing adequate voltage, the battery can’t deliver enough current, resulting in no effective amperage.
