That’s measured by the amps (A) in a current. Voltage is how steep and long the hill is, so how fast the electrons may be when they reach the bottom.īut voltage doesn’t tell us how many electrons are actually rolling down the hill. Imagine a current as electrons rolling downhill. Voltage measures the potential for energy in a circuit. If you know that the typical household current runs at about 120 V, you may think this is a lot, but it’s no reason for concern, because voltage is only part of what determines the energy in an electric current.Īn electric current is when electrons move. The current created by a TENS units may have a voltage range that goes up to 200 mA. TENS uses a very low-powered current that is safe for regular use and a method our office uses for TMJ Treatment. TENS, transcutaneous electrical nerve stimulation, is commonly used to treat the muscle tension in TMJ and other types of chronic pain.
