The resistance of a component can be calculated using the formula: ``` Resistance (Ω) = Voltage (V) / Current (A) ``` Ohm's Law These formulas are collectively known as Ohm's Law, named after the German physicist Georg Ohm. Ohm's Law provides a fundamental relationship between...
Combining the elements of voltage, current, and resistance, Ohm developed the formula: Where V = Voltage in volts I = Current in amps R = Resistance in ohms This is called Ohm's law. Let's say, for example, that we have a circuit with the potential of 1 volt, a current of 1 amp...
current flowing through the resistor are the same voltage U.2. circuit is equal to the resistor voltage and total resistance R U=U1+U2+U33. series circuit is equal to the series resistance of N and R=R1+R2+R3 if a resistor in series, the equivalent resistance of R R=R1+R2+R3+.....
