Dear student.
In electrical synapses, the pre and post synaptic neurons lie in close proximity to each other. Hence, the impulse can move directly from one neuron to another across the synapse. This represents a faster method of impulse transmission.
Major terms are synapse, impulse, gap junction , membrane potential , depolarization, hyperpolarization, voltage-gated ion channels, bidirectional transmission​ etc.
Regards.
