Question
Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistor of 2Ω in series with a combination of two resistors (4Ω each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2Ω resistor be the same as that across the parallel combination of 4Ω resistors? Give reason.
Solution
Net resistance of two 4Ω resistors connected in parallel is 2Ω. Since we have two resistors of same resistance in series so the potential drop across each one of them will be same.

What are the essential components of an electric circuit?
An electric motor rated 1100 W is connected to 220 V mains. Find:
- The current drawn from the mains,
- Electric energy consumed if the motor is used for 5 hours daily for 6 days.
- Total cost of energy consumed if the rate of one unit is 5.
Set up the circuit shown in Figure again. Move the key to ‘ON’ position and watch carefully in which direction the compass needle gets deflected. Switch ‘OFF’ the current. Now keeping rest of the circuit intact, reverse the connections at the terminal of the cell. Again switch ‘on’ the current. Note the direction in which the needle gets deflected. Think of an explanation.
