Yes, heat energy is produced by the electrons;however small it may be,actually if we consider a resistance then it is an hindered to the flow of electrons,as a result of which the electrons collide with the particles of wire resulting in loss of energy in the form of heat.the equation of heat generated is:
H=(I^2 *R*t)
where-
H=heat produced in joules
R=resistance of the material in ohm
t=time of current flow in seconds
In a parallel circuit the current divides when it comes to a junction. Part of the current flows through one branch and the other part flows through the other.When the two branches have the same resistance, the same current flows through each branch.When the two branches have different resistances, a bigger current flows through the branch with the smaller resistance - it's just easier this way!Hope i helped ;)
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
True
Metals that make up typical resistors (and many other electrical components for that matter) tend to heat up as current flows through them. "COLD" resistance is the resistance before it is operating and "HOT" resistance is the resistance after some operating time has elapsed.
The resistance of a current is a measure of how difficult it is to push the electrons along.AnswerThere is no such thing as the 'resistance of a current'. Resistance is a characteristic of the material through which a current flows, not of the current itself.
The amount of heat produced in an electric wire depends on its resistance, the current flowing through it, and the duration for which the current flows. The formula for calculating heat generated in a wire is H = I^2 * R * t, where H is the heat produced, I is the current, R is the resistance, and t is the time.
As electricity flows through a wire, resistance causes some of the electrical energy to be converted into heat. The heat produced is proportional to the amount of current flowing through the wire and the resistance of the wire. Higher resistance in the wire will result in more heat being generated.
The heat produced due to electric current through a resistance is i) directly proportional to the square of the current ii) directly proportional to the resistance value of the conductor iii) directly proportional to the time of flow of current.
voltagei=v/r
Typically resistance rises with temperature.

When an electrical current flows through a wire, it creates a magnetic field around the wire.
No, current does not flow through a circuit by taking the path of least resistance. Instead, current flows through all available paths in a circuit, with the amount of current in each path determined by the resistance of that path.
5amps of current will flow it
A magnetic field is produced around a wire when an electric current flows through it. This magnetic field is directed along circular lines around the wire.
