Time Delay Relay Using IC 555
... The 555 output will supply up to 200mA of current, so the relay could be replaced with a small lamp, doorbell, or other load that requires less than 200mA. When the button is released, the 0.1uF capacitor discharges through the 100K and 2K resistors. The diode across the 100K resistor prevents the v ...

Measuring Voltages and Currents
... In an ideal case, the ammeter will not produce a voltage across itself. This is equivalent to stating that an ideal ammeter looks like a short circuit (i.e. the resistance across it is zero). This is because if it did develop a voltage, it would change the values of the currents and voltages across ...
