Question

Explain the variation of current (I) and resistance (R)​

Answer 1

Answer:

Here is the answer for your question

Explanation:

When an external resistance is connected to an electrolyte then there is a voltage drop in the resistance so the voltage across will reduce. When we plot a graph showing the variation of current versus voltage it is a straight line with a lesser slope. It is due to the presence of external resistance which implies for flowing the same current in the circuit with external resistance require more voltage than the circuit without resistance.
