Yes, Ohms law is applicable in altering current.
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
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
because they have a proportional relation
Current density is unrelated to Ohm's Law.
Ohm's Law is not applicable to open circuits because there is no current flow. Ohm's Law specifically describes the relationship between voltage, current, and resistance in a closed electrical circuit.
Current = voltage/resistance
Temperature. Ohms law is applicable to measure resistance of an element at constant temperature only.
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.
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.
