Answer:
Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.
If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.
If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.
B.a definite shape,but no definite volume
C.No definite shape,but a definite volume
D.no definite shape and no definite volume
A substance in the solid phase (state) of matter has a definite shape and a definite volume.
Volume is the amount of space taken up by an object, while capacity is the measure of an object's ability to hold a substance, like a solid, a liquid or a gas. Volume is measured in cubic units, while capacity can be measured in almost every other unit, including litres, gallons, pounds, etc.
Matter in the solid-state maintains a fixed volume and shape, with component particles (atoms, molecules or ions) close together and fixed into place.
Hence, option A is correct.
