Â­TheÂ­ three most basic units in electricity are voltage (V), current (I, uppercase i) and resistance (r). Voltage is measured in volts, current is measured in amps and resistance is measured in ohms. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. How Power Grids Works.
Biofeedback is a method that uses the mind to control a body function that the body normally regulates automatically, such as skin temperature, muscle tension, heart rate, or blood pressure. When you are first learning biofeedback, you will have sensors attached to your body and to a monitoring device.
Alpha Brainwave Feedback. Alpha wave biofeedback is a type of feedback that measures the alpha waves of the brain. Through this kind of monitoring, one would be able to control the amount and frequency of the alpha waves and create a relaxed and positive mental state for oneself.n a sense, a person learns to control their brain waves. However, keep in mind that with brain wave therapy one is not controlling the actual electrical and synaptic connections in the brain, but rather a person learns to control the subjective events that the brain associates with Alpha signals.
