Heat
Could be the wires, but more so anything that makes heat or light, like a stove, light bulb, or electric blanket.
Power source such as a battery if u pluged it in it will supply energy to drive electric charges around a circuit
source
circuit is the complete path of an electric current including the source of electric energy.
In the circuit it is connected to other devices with their own properties that can influence your reading. Out of circuit you just measure the resistor. It has the same value both ways.
An electrical circuit is a path which electrons from a current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". ---Nerd
a power source, path, and load or resistance.
A: As current approaches infinity on a device it is known as a current source.
A path that is made for an electric current is called a circuit. The two main components in a circuit are the load and a source which are combined with conductors and as a whole form a circuit.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
Battery
Anything with a voltage power source, connecting wire and a load is an electric circuit. Hence if you have a flashlight you have an electric circuit.
power source
The first thing you need to know is the internal resistance of the current source, the voltage source will have the same internal resistance. Then compute the open circuit voltage of the current source, this will be the voltage of the voltage source. You are now done.
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
Voltage will be constant. Resistance is dependent on the components in the circuit. Source: Electronics Technician for the US Govt
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
Electric currents flow from the source through the circuit and back to the source in materials called conductors.
