In Volta's cell, what is positive electrode (anode) made up of?

When do we say that the resistors are connected in parallel ?

Calculate the equivalent resistance between the points $A$ and $B$ in the following combination.

What is the power of a bulb rated at $2.5 \,V$ $500\, mA$ ?

Find out the following in the electric circuit given in Figure.

$(a)$ Effective resistance of two $8\,\Omega $ resistors in the combination

$(b) $ Current flowing through $4\,\Omega $ resistor

$(c)$ Potential difference across $4\,\Omega $ resistance

$(d)$ Power dissipated in $4\,\Omega $ resistor

$(e)$ Difference in ammeter readings, if any.

The flow of charge through a conducting wire connected to a cell is the result of chemical reaction inside the cell.
