Getelectric, another easy way to remmember this.
Static electricity runs in the thousands of volts. If you walk across the carpet and then touch something, and Zap, that's static electricity. But there are no amps to be pushed, very liitle current very high voltage.

Lightning runs in the millions of volts, lot more amps. Don't get Zapped by that.

Tazers, stun guns, same principle.
50,000V knock you down pretty quick, very little current.
