D.C. stands for direct current. A.C. is alternating current.
A: Those voltages are called distribution voltages to differentiate from transmission voltages. And that varies from state to state and locals . Usually around 10kv to 20 kv
Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.
Cell phone voltages are DC5V-5.5V
Digital
The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.
Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.
What two voltages are present on a peripheral power connector?
A: Alternating voltages means the phase factor must be considered.
The slope of a voltage vs. current graph represents the resistance in the circuit. It indicates how the voltage changes with respect to the current flowing through the circuit. A steeper slope indicates higher resistance, while a shallower slope indicates lower resistance.
Power lines run at high voltages to overcome line loss.
A: Voltages varies on a circuit because current varies caused by difference in resistance
The Fluke T5 is voltage continuity and current tester, meaning that its purpose is to test the voltages, ohms and amps of electrical devices used primarily by electricians.
