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?

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

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

When a 12V battery is connected across an unknown resistor, there is a current of 2.5 mA in the circuit. Find the value of the resistance of the resistor.

A resistor of 100Omega and a capacitor of 20/pi muF are connected in series to a 230V, 50Hz ac source. Calculate the current in the circuit. Also calculate the voltafge (rms) across the resistor and the capacitor.

A capacitor and resistor are connected in series with an ac source. If the potential difference across C and R are 120 V and 90V respectively and if the rms current of the circuit is 3A, calculate (i) impedance and (ii) power factor of the circuit.
