multimeter
If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.
Lead-Acid Battery Basics
An ideal battery (without internal resistance) is one in which the voltage is a constant independent of the current provided. A real battery has some internal resistance. The equivalent circuit model for a real battery is an ideal battery in series with internal resistance. Figure 1. Equivalent circuit of a real battery.

Science Simplified: What Is a Battery?
What Is a Battery? Batteries power our lives by transforming energy from one type to another. Whether a traditional disposable battery (e.g., AA) or a rechargeable lithium-ion battery (used in cell phones, laptops, and cars), a battery stores chemical energy and releases electrical energy. Th
Lithium-ion battery
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a …
current
A typical CR2032 can source much more current than 5 mA. You could pull 100mA from it, for under an hour, with some caveats about it''s high ESR. The nominal current is to establish a base lifetime of the battery. CR2032, and coin cells in general, are meant for low current, long life applications, like real time clocks or battery backups of …
Back Emf | Physics
Under normal operating conditions for this motor, suppose the back emf is 40.0 V. Then at operating speed, the total voltage across the coils is 8.0 V (48.0 V minus the 40.0 V back emf), and the current drawn is I = V/R = (8.0 V)/(0.400 Ω) = 20 A. Under normal load, then, the power dissipated is P = IV = (20 A)/(8.0 V) = 160 W. The latter will ...
