I or J = Latin: influare or international ampere.
Another source gives the origin of the I as being from the German word for Intensity.
Yes, Ohms law is applicable in altering current.
Ohms law
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
voltage! measured in volts. current X resistance = voltage simple ohms law
Current
Yes, Ohms law is applicable in altering current.
Current density is unrelated to Ohm's Law.
Current = voltage/resistance
They are the three components that are used in Ohms law. Knowing any two will lead to the calculation of the third.
Ohms law
The mathematical form of Ohms law is I=V divided by R. I is current, V is voltage while R is the resistance.
Ohms law. R = E/I,where R= resistance in ohms, E = voltage in volts, and I = current in amperes.
Ohm's Law: Resistance is voltage divided by current 110 volts divided by 0.4 amperes is 275 ohms.
Just use Ohms Law: V=IR, that is, voltage (in Volt) = current (in Ampere) x resistance (in Ohms).
The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A)
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
