There is no relation between the value of a resistance and whatever name you choose to call such a thing. But traditionally, for obvious reasons, use of the small letter r means there is an expectation that it will be smaller than one called R.
unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance unit of internal resistasnce is ohms too. V = I(R+r) V voltage across the circuit I current in the circuit R external resistance r internal resistance
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
No, it is less. Use the formula:1/R = 1/R1 + 1/R2 + 1/R3...Where R is the total (equivalent) resistance for the parallel circuit,and R1, R2, etc. are the individual resistance.No, it is less. Use the formula:1/R = 1/R1 + 1/R2 + 1/R3...Where R is the total (equivalent) resistance for the parallel circuit,and R1, R2, etc. are the individual resistance.No, it is less.

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.

The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
R=1/(1/ R1 +1/ R2 +1/ R3 +.........) Where R is the total external resistance(effective resistance) in an electric circuit.
R=1/(1/ R1 +1/ R2 +1/ R3 +.........) Where R is the total external resistance(effective resistance) in an electric circuit.
The maximum voltage formula for a circuit is V I R, where V is the voltage, I is the current, and R is the resistance.
The relationship between power (P), current (i), and resistance (r) in an electrical circuit is described by the formula P i2 r. This means that power is directly proportional to the square of the current and the resistance in the circuit.
r=r1+r2+..............
The formula for calculating the resistance of a capacitor in an electrical circuit is R 1 / (2 f C), where R is the resistance, f is the frequency of the circuit, and C is the capacitance of the capacitor.
E = I* R is Ohm's Law. Where: E = voltage I = current R = resistance Using simple algebra yields: R = E / I
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
That entirely depends on whether the resistances are in series or in parallel with each other. Ohm's law states that I=V/R. i.e. current = voltage/resistance. If you know the current and voltage you can find the resistance. You can use algebra to rearrange the formula for R and get that R= V/I. Resistance = voltage/current.
