You are provided with a torch bulb, a cell and two plastic coated metal wires. Draw a diagram to show a complete circuit to light the bulb.
Draw a circuit diagram when three bulbs are connected in series with a battery of cells, which are also connected in series.
Draw a circuit diagram for a bulb connected to a cell with a switch. Mark arrows in the diagram to indicate the direction of flow of current.
Draw a circuit diagram of an electric circuit containing a cell, a key, an ammeter, a resistance of 2 Omega in series with a combination of two resistors ( 4 Omega each) in parallel and a voltmeter across the parallel combination. Will the potential difference across the 2 Omega resistor be the same as that across the parallel combination of 4 Omega resistors ? Give reason.
