With a 1-W load, the voltage at the terminals of a certain voltage source is found to be 10V; without the load, is rises to 10.2 V. Estimate Vs and Rs. Hence, predict the voltage at the terminals of the source for the case of a 22 Ohm load.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
