A relay race could be a good model of a series circuit. In any circuit, current flow is the daisy-chaining of electrons from atom to atom.
The letter R is used to represent resistance. For instance, the R in a circuit is said to be 52 ohms. Just that simple.
A 'model' simplified circuit is a circuit that performs very closely to a real, usually far more complicated circuit. Model circuits are used to help analyse the behaviour of more complicated circuits. Often, there are various models which make different assumptions about the actual circuit, in many cases offering various degree of simplification. For example, there are several different model circuits that represent a transformer, with the simplest model assuming that the transformer has absolutely no losses whatsoever, and the more complicated models taking into account those losses. Another example of a model circuit is when we represent, for example, an inductor in terms of its inductance and resistance with these quantities being connected in either series or parallel.
The current through the circuit is directly proportional to the voltage across the circuit. The proportionality constant is 1/R, where 'R' is the total effective resistance of the circuit. C = V / R V = C R R = V / C
It is a model for the equivalent circuit of a Transistor.

An RL circuit is a circuit containing resistance (R) and an inductance (L).
How is the central heating model not like an electric circuit?
how its the same
The formula for calculating power loss in a circuit is P i2 R, where P represents power loss, i is the current flowing through the circuit, and R is the resistance of the circuit.
r=r1+r2+..............
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.
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
The equation for current flow (I) in a circuit is given by Ohm's Law: I = V/R, where V is the voltage across the circuit and R is the resistance of the circuit. This equation states that the current flowing through a circuit is directly proportional to the voltage across it and inversely proportional to the resistance of the circuit.
Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.
The formula for instantaneous current (i) in a circuit is given by Ohm's law: i = V / R, where V is the voltage across the circuit and R is the resistance.
