Explanation :
An electrical circuit can be either connected in series or parallel.
Series combination: The current flowing in each resistor is the same and the equivalent resistance is given by :
Parallel combination: The voltage for all components in the parallel combination is the same. The equivalent resistance is given by :
So, our of given options the correct one is (b) because the current flowing in both the resistors is the same.
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.
Solids can be hard like a rock, soft like fur, a big rock like an asteroid, or small rocks like grains of sand. The key is that solids hold their shape and they don't flow like a liquid.
