Use the formula P = I2R (I = current; R = resistance).
E = I R = 3 x 4 = 12 volts
p=i^r
p=3*3*4=36w
36 W
we can calculate the current in a commmon electrical circuit by this formulae i.e,I=V\R where i is the current flowing in the conductor, R is resistance , V is the voltage.. THE FORMULA IS CORRECT but the term conductor does not suffice an explanation since a conductor is low in resistance R= resistance not conduction.
Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance
If you don't change the voltage between the ends of the circuit,then higher resistance in the circuit means lower current (amps).
The resistance of the circuit will be 46 ohms

The formula you are looking for is Ohms = Volts/Amps. R = E/I.
You don't have enough information in your question, you need to include the voltage as well. One relevant equation is V = I * R where V: Voltage, I: Amps, and R: Resistance. When you have the voltage divide the Ohm resistance into that and you'll get your amps.
Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)
Amps Ohm's law states the current is directly proportional to the applied emf (voltage) and inversely proportional to the resistance of the circuit.
If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
