WebVoltage is a measure of the energy carried by the charge . Strictly: voltage is the 'energy per unit charge'. The proper name for voltage is potential difference or p.d. for short, but this term is rarely used in electronics. Voltage is supplied by the battery (or power supply). Voltage is used up in components, but not in wires. WebMar 14, 2024 · The resistors in Figure 1 don't know anything about where your ground reference is. From the resistor's point of view each of the circuits in Figure 1 are the same. There is a 4 V potential difference across it with the left side 4 V higher than the right. Therefore 4 mA will flow from left to right in each case. eashing bridgeWebSep 12, 2024 · Figure 11.7. 1: In the Hall effect, a potential difference between the top and bottom edges of the metal strip is produced when moving charge carriers are deflected by the magnetic field.
