Want this question answered?
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.
The total current decreases.According to the Ohm's law the current & the resistance are inversely proportional so when we put a load in series with the existing load, the resistance of the circuit increases therefor the current decreases.
Resistance of the circuit = (voltage across the circuit) divided by (current through the circuit)
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
Ohm's Law: Resistance = voltage / current, so 12 / 3 = 4 ohms.
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
You don't. If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms). EMF stands for Electromotive Force, and its unit of measure is the Volt.
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).

The formula you are looking for is Ohms = Volts/Amps. R = E/I.

Simply put, the purpose of a resistor is to 'resist' the flow of current. Ohm's Law tells us that for a given voltage, the larger the resistance, or value of that resistor, the lower the current that will flow. Ohm's Law states that I (current) = E (voltage) / R (resistance) - where current is measured in amps, voltage is measured in volts and resistance is measured in ohms.
