$I.$ Pre and postsynaptic membrane neurons are in very close proximity at electric synapse
$II.$ Electric current are involved in the transmission of impulses
$III.$ Transmission of an impulse across electrical synapses is very similar to impulse conduction along a single axon
$IV.$ Impulse transmission is always faster in electric synapse than that across a chemical synapse
$V.$ Electrical synapses are rare in our system
