Factors that influence the electrode response time

2 Factors that influence the electrode response time 

However, there are a number of practical problems associated with the design and fabrication of microelectrodes that cause micron-sized electrodes to have RC time constants that greatly exceed those predicted by equation (6.1.1.1). 

Effect of nonideal microelectrode geometry on resistance and capacitance  

Elliptical (IB) t Capacitance increases but resistance decreases relative to ideal due to increased electrode area.
