Explanation:

A conductor allows electric current to pass through it. Hence, when conductors are connected in a closed circuit, current flows.

All the resistors in Q2 are connected in series. In a series connection, the current across all the resistors is the same.

In a battery, chemical energy is converted to electrical energy by chemical reactions.

When a new resistor is connected in parallel to a circuit the current increases accordingly.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;
