Types of Electric Circuit
Q. Is energy stored in a resistor?
Power in Resistors. When a current flows through a resistor, electrical energy is converted into HEAT energy. The heat generated in the components of a circuit, all of which possess at least some resistance, is dissipated into the air around the components.

Q. What are the five elements needed for a practical circuit?
What are the five elements needed for a practical circuit? load, source, circuit control device/switch, conductor, circuit protection device/fuse.
- Close Circuit. When load works on its own in a circuit then it is called Close Circuit or Closed Circuit.
- Open Circuit. When there is a faulty electrical wire or electronic component in a circuit or the switch is OFF, then it is called Open Circuit.
- Short Circuit.
- Series Circuit.
- Parallel Circuit.
Q. What is the common wire in a 3 way switch?
The single dark-colored screw is known as the common terminal. The ground screw is usually green. The arrangement of these screws varies depending on the switch manufacturer. On some 3-way switches, the two traveler screws are on one side of the switch body, with the common screw isolated on the other side.
Q. Is the common wire negative or positive?
The common wire is the ground or negative wire. To complete the circuit that provides power to the thermostat you need a positive and negative wire from the 24V transformer. Some thermostats have batteries that power them and they serve only as a switch to operate the heating or cooling unit.
Q. What color is positive wire?
red
Q. What does it mean if voltage is negative?
A negative voltage is a relative excess of electrons compared to some other point. If 0 V is no voltage. Negative voltage is an excess of electrons and positive voltage is a deficiency of electrons.
Q. What is the difference between positive and negative voltage?
A voltage source has positive or negative polarity depending on its orientation in a circuit. The first circuit is positive voltage because the positive end of the voltage is connected to the positive end of the source is not connected to ground, while the negative end of the voltage source is connected to ground.
Q. Is 0 volts positive or negative?
Voltage at a point and 0V (zero volts) Zero volts could be any point in the circuit, but to be consistent it is normally the negative terminal of the battery or power supply. You will often see circuit diagrams labelled with 0V as a reminder.
Q. What flows from negative to positive?
Current is flow of electrons, but current and electron flow in the opposite direction. Current flows from positive to negative and electron flows from negative to positive.
