Battery Drain



I am trying to figure out the battery drain in a simple circuit. Can I see the voltage and miliamp hour draw over time? I would like to use Mulitsim to compare 2 different brands of 9 volt batteries.

Hi Joseph,


I think it will be difficult to measure the battery drain over the time with the circuit you provided, since the spice model used for the battery is an ideal behavior of a battery. On Multisim 14.0.1 there is a non-Ideal battery. you can try to simulate the behavior using this component. 


Take a look at the link below.
