In this week’s Gizmodo University: Discover Electronics, we’re diving headfirst into the principle theories of electronics. The second of four classes in this series, “Volts, Amps, and Ohms” is ...

Voltage and Current divider arrangements are the common in electronic circuits. Before selecting the value of resistors, it is necessary to calculate the voltage and current from the output of a ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Electrical current is electrical charge transferred in a particular time. These three properties can be calculated using the equation Q=It. Current can be a.c. or d.c. Revise: Potential differences ...

Today, portable applications have many unique battery requirements. They require a high-energy density to provide unlimited power (both transient and continuous). They need to be lightweight with ...
