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.

What is the unit of measurement of 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 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
Resistance in a circuit and in ohms law is represented by the letter?
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
The total resistance in a parallel circuit is the smallest resistor in the circuit?
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.

What factors determine the voltage induced in a wire?
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.
What is the realtionship among voltage current and resistance in a circuit?
Ohm's Law Voltage = Current x Resistance

What is RL circuit in ac voltage?
An RL circuit is a circuit containing resistance (R) and an inductance (L).
What is the formula for calculating the equivalent resistance of a series circuit?
Equivalent resistance of a series circuit is the sum of the resistance of all appliances. The formula is R=R1+R2+... where R is equivalent resistance, R1, R2 and so on is the resistance of the individual appliances.

How do you find the power of a bulb when potential difference and current is given?
E = Voltage of the circuit I = Current in the circuit R = Resistance in the circuit Ohm's Law states that given two variables in an electric circuit, the third can be calculated: R=E/I I=E/R E=I*R Power in any circuit can be calculated by one of the following: P=E*I P=I2*R P=E2/R
The circuit you are working on has a resistance of 25 ohms and a current of 14 amps What is the voltage?
Ohm's Law states that I = E/R where I is current in amps, E is voltage, and R is equal to the circuit resistance in ohms. Rearranging the equation to solve for E results in E = I*R. Replacing I with 14 and R with 25 results in the circuit voltage being equal to 350V.
