If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

Modern CPUs require supply voltages of 1.5V and below and currents of up to 100A. This power frequently originates from the 12V output of a “silver box” power supply. Developing the lower voltage ...

Originally, current was defined as the flow of charges from positive to negative. Scientists later discovered that current is actually the flow of electrons, from negative to positive. The original ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...
