Light bulb

Explanation:

In an electric circuit, a battery provides potential difference across the circuit when it is connected between the positive and negative terminals of the battery.

A switch is used to open or close a circuit. when open, no current flows through the circuit.

A wire connects all the components of the circuit. Current flows through the wires.

A light bulb provides resistance in the circuit.

According to Ohm's law:

V = I R

A light bulb glows because energy is dissipated in the form of heat and light to overcome the resistance offered by the bulb. Bulb has resistance R. When current I flows through it, rate of energy consumed:

Power, P = I² R

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
