When electric charges flow through the wires and loads of the circuits they encounter resistance or a hindrance to their movement. So another factor that affects the flow of charges or current is resistance. The symbol for resistance is capital letter R. The unit, ohms (Ω) is named after the German physicist Georg Simon Ohm.In which circuit did you observe a brighter light bulb?*1 pointCircuit with one light bulbThe bulb did not light up in any of the circuits.The brightness of the bulbs in the two circuits are the same.Circuit with two light bulbs

A simple circuit exists with one light bulb. A resistor of equal resistance to the bulb gets placed in the circuit in parallel. Which of the following would occur? The current would increase. The total voltage would decrease. The current would stay the same. The total resistance would remain the same.

A small bulb has a resistance of 2Ω when cold. It takes up a current of 0.4 A from a source of 4V and then starts glowing. Calculate (i) the resistance of the bulb when it is glowing and(ii)  Elaborate on the reason for the difference in resistance?

In which circuit did you observe a brighter light bulb?*1 pointCircuit with two dry cellsCircuit with one dry cellThe brightness of the bulbs in the two circuits are the same.The bulb did not light up in any of the circuits.

When two identical lamps in a circuit are connected in parallel, the equivalent combined resistance is​more than the resistance of either lamp.​Group of answer choicesTrueFalse

An electrical load is an component of a circuit that uses the electrical energy. Common example is an household appliance consuming electrical energy.  In the case of the circuits investigated in this experiment, bulb serves as the load. Adding a bulb in a circuit increases the resistance.What can you infer about the resistance present in the two circuits tested?*1 pointThe resistance in the two circuits are the same.The resistance in the two circuits is zero.The resistance is higher in the circuit with two light bulbs.The resistance is higher in the circuit with one light bulb.
