Though it generally is not a good idea to insert objects into a wall outlet, a multimete...Current (measured in Amps, Milliamps, etc.) is the measure of how fast electrons are passing through a circuit. Capacity (measured in "Amp hours", "Milliamp hours", etc) is the measure of how long a power storage device can supply a certain current. It is roughly true to say that a 1000mAh battery could output 1000mA for 1 hour or 1mA …

1. Set the multimeter to Ohms or Resistance. Turn the meter on if it has a separate power switch. When multimeter measures resistance in ohms, it can not measure continuity because resistance and continuity are opposites. When there is little resistance, there will be a great deal of continuity, and vice versa.

Set the Multimeter’s Control Knob to Read Direct Current. Clip the red lead to the unconnected end of the resistor. Clip the black lead to the negative terminal of the battery. It will give a positive reading. Start the stop watch. Read the stop watch after every hour until the current is 70 percent.

1. Set the multimeter to measure capacitance. Most digital multimeters use a symbol similar to –| (– to signify capacitance. Move the dial to that symbol. If several symbols share that spot on the dial, you may need to press a button to cycle between them until the capacitance symbol appears on the screen. [3]After integrating the multimeter into the circuit, you can restore power. As the current flows through it, you should notice a number on your device’s display.
