In series circuit, potential difference across each resistor is always the same.

Redraw the circuit of Question 1, putting in an ammeter to measure the current throuch the resistor and a voltameter to measure the potential difference across the 12Omega resistor. What would be the reading in the ammeter and the voltameter?

How is potential difference generated?

Is potential difference a vector or a scalar quantity?

200J of heat is produced each second in a 5Omega resistance. Find the potential difference across the resistor.

Let the resistance of an electrical component remains constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it?

Three capacitors whose capacitances are 5, 10 and 50 microfarads are connected in series across a 12 volt battery. Find the potential difference across each of them.
