RCES Review: Basic EP Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
Amps The flow of electric current
1 coulomb/sec Amps. Electric flow is expressed this way
like
hemodynamic flow is expressed in L/min
Impedance Total opposition to flow of alternating
current in a
circuit (ohms) or resistance
When impedance rises during RF It means something is increasing in the
ablation... resistance
to current flow (char on the electrode tip,
loss of
tissue contact...)
Most common D.C. Electric power Battery
source
Only travels in one direction D.C. Power; flows steadily from - to +. It
does not
alternate back and forth like AC current
