You must know the applied voltage to determine the answer. According to Ohm's law:
I = E/R (current equals voltage divided by resistance)
So, if the voltage were, say, 16 volts, then the current through the 8 ohm resistor would be two amps:
2 = 16 / 8
You are trying to compare apples with elephants. Ohms is a measure of resistance and amps measures current.
There are two important formulas when calculating Voltage, Current, Resistance and wattage. Ohm's Law states that Voltage = Current x Resistance; and Watts = Current x Voltage x PF, where PF is the power factor and has a value from zero to 1. For a purely resistive load the PF is 1 so the formula is simplified to Watts = Current x Voltage. PF decreases for loads like motors or lights with ballasts.
Ohms(R) is the amount of resistance of the load in a given circuit, where as, amps(I) is the amount the load uses in current, ie: a 60 watt(P) light bulb uses half an amp at 120 volts(E) AC. Using the 'PIE' method, P / I X E 60 / .5 X 120, if you place = at any of the other signs, the sum will equal the means, now solve for the ohms value using E / I X R, 120 / .5 = 240. This is the simplest form to finding the value of a circuit. So, the answer to the question is, they are two totally independent things that are bound to each other and inversely affect one another, in a circuit. If ohms increases, current decreases when voltage stays the same, as when ohms decreases, current increases with the voltage staying the same.
According to Ohm's law,
I=E/R
meaning current (amps) equals voltage (volts) divided by resistance (ohms).
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms
voltage! measured in volts. current X resistance = voltage simple ohms law
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps
ohms=amps/volts Amps= volts/ohms Volts = Amps*Ohms
Ohm's Law: Voltage = Amperes times Resistance 9 volts = amps * 10 ohms amps = .9
Using Ohms Law, the answer is 120/0.5 = 240 Ohms.
Amps and volts are not the same, but related by Ohm's Law. Volts = Amps x Ohms. Ohms is a measure of resistance. Given .01 amps you would have to know resistance to calculate volts.
Using Ohms law, the resistance can be calculated by using the following formulas. R = Watts/Amps (squared). R = Volts (squared)/Watts. R = Volts/Amps.
The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A)
Ohms. It can also be calculated using Ohm's Law. V=I/R where V is voltage in Volts, I is current in Amps, and R is resistance in Ohms.
Just use Ohm's Law: V=IR (voltage = current x resistance; using units: volts = amperes x ohms).
Current is inversely proportional to resistance. If you double the resistance, you halve the current. Ohm's Law: Volts = Amps * Ohms Solve for Amps: Amps = Volts / Ohms
Google Ohms Law. It will give you all the formulas you need to compute Ohms,Volts and Amps. Simple formulas :-)
To find the conductance using ohms law,you take the inverse of the resistance(/R)
