What is the Ohm Law?
Ohm discovered that the amount of current was directly proportional to the voltage (more voltage gives more current) and inversely proportional to the resistance (more resistance gives less current).
Current = Voltage / Resistance
I = V/R (or V = IR, R = V/I)
This relationship is called Ohm's Law. It also gives us a relationship between the units amperes, volts and ohms:
1 ampere = 1 (volt/ohm)
Consider an x-ray tube in which electrons are accelerated by a constant high voltage of 250 kV. If the electron beam current is 10 mA, calculate the x-ray energy flux (energy fluen
Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
