# How can you have high voltage and low current

I’ve read in another article, that you can have low current and high voltage simply by having a resistor in your circuit. From what I understand, current is the flow of electrons and voltage is the energy is how much energy is transferred per unit charge. I think the current comes from energy that moves the electrons - kinetic energy(?). Now if we add a resistor which slows down the current, then the electrons will lose energy and therefore voltage will drop too since V=E/Q. This doesn’t make much sense to me can someone explain what’s going on here?

• a resistor does not slow down the current ... it only reduces the amount of current – jsotola Dec 23 '18 at 6:42
• WIth really good insulation you have no current leakage, just a static charge. – Sunnyskyguy EE75 Dec 23 '18 at 8:03
• @jsotola, current is a flow of electrons, which is slowed down: $i=\frac{dq}{dt}$ – Chu Dec 23 '18 at 8:07
• @Chu electrons travel at the same speed, but current is the amount of electrons going past a point in a given time - do you think that is what jstola means? – Solar Mike Dec 23 '18 at 9:14
