What component is NOT part of an electric IED?

The component that is not part of an electric improvised explosive device (IED) is the timer. In an electric IED, the power supply is crucial as it provides the energy required to initiate the device. The initiator is also essential, serving to create the necessary conditions for detonating the explosives when the device is activated. The explosives themselves are the primary harmful payload of the IED.

A timer is generally associated with IEDs that are designed for delayed detonation, allowing for a specific timing of the explosion. However, in the context of an electric IED, which operates based on electrical signals, immediate detonation is often more common. Therefore, the timer, while it can be a component of some IEDs, does not fit the typical construction of an electric IED setup.
