A setting of 85 kVp is equal to how many volts?a. 850b. 8500c. 85,000d. 850,000e. 8,500,000
True / False. True / Falsevoltage is the measurement of the number of electrons flowing in an electrical circuit. Decreasing the voltage decreases the force that moves the electrons along an electrical conductor.
True / False. True / FalseThe cathode is the electrically negative portion of the vacuum tube, and it is composed of a focusing cup and filament.
